Super fast made my truck 10 times better

Truck drives great after getting tuned,happy with the performance!

Have had my tunes for a few weeks now and absolutely love them especially the transmission tuning compared to the canned hydra tunes. Was having a shift flare from 3rd to 4th and these completely cleared that up. Also can’t believe how smooth and how well it shifts when you stand on it and get into boost. Highly recommend these tunes if you’re on the fence about it.
Craig C.
Awesome customer service and amazing tunes.
Ron S.
Brian worked with me to get my 02’ running and shifting great through multiple tunes. Jelibuilt has a great reputation for a reason.
Carson O.
Jelibuilt has my heart. These tunes are amazing. I will never shop anywhere else for my truck
Morgon W.
Loving all the options so far!
George E.
I have not towed with it yet but I can tell the difference in the engine. I am looking forward to towing to really test the truck but I am happy with my results it has been a three year journey but it’s hard for me to believe I am there, thank to all the online diesel stores and jelibuilt for bringing it all together.
Paul M.
Great people to deal with help me out a lot would recommend them
Austin C.
Extremely happy with the tunes and the experience overall. Brian was super helpful and timely when it came to revisions and got all the tunes just how I wanted them. Would absolutely recommend and will continue to use Jelibuilt in the future
THRON M.
Very professional correspondence with Jelibuilt. Fast tuning sent to email. “Drag ripper tune” has very good throttle response, good shifting manners, and good converter lock-up.
Ethan S.
INSTANT THROTTLE RESPONSE!!! brought my dinosaur of a truck (02 7.3) back to life! Now walks my buddies lml which is crazy thanks jelibuilt!
Alec A.
I bought a hydra tuner for my mostly stock 97 7.3l. I used the box tunes for a week and decided to give Jelibuilt tunes a try. I purchased a daily driver tune and I am happy to say it is way better than any of the box tunes. Much better shift points and way smother throttle control with a little more power overall. I wish I would have started with jelibuilt from the beginning. I will be purchasing more tunes in the future.
Cody W.
Was quick and simple . Emailed them exactly what I wanted and they delivered. Swapped the truck from the auto to the manual and they were able to write custom tunes to make the truck idle right and not have a hesitation anymore . Will be using them for all my tuning needs .
Alexander E.
Great tuning... Truck is much more predictable to drive now.. Very satisfied with it. The Strenuous tow rune will help tremendously pulling our Skid steer which is 12k lbs in itself.. Has the power of a 6.7 and 10 times the reliability now!
Devin H.
I had hard shifting, weird shift points and blew my torque converter pulling a mid weight trailer.
Rick P.
Everyone was extremely helpful and did exactly what I asked them to do. My truck has never run better. Couldn't be happier.
William G.
Brian was awesome. He wrote some custom tunes for an uncommon PCM code that helped me take care of some issues I was having with other tuners.
Brennen K.
Tows better without worrying about egts
Nicholas S.
Work great performance is awesome
Chris H.
Great Service
The tunes are awesome!!
Chance E.
I really like the hot street tune. Sounds great, less smoke than the other tunes I have.
Brandon H.
Worked excellent!
Denis A.
Amazing customer service and tunes to match definitely recommend
Nathaniel
Revisions made it a good overall tune
mario c.
Hi I still haven’t had a good chance to see how it performs but when I get back from my trip in November I’ll let you know
Thank you
Aidan N.
Tunes are great truck runs very smooth
Brandon J.
I’ve only drove it a few times so far and only pulled for a short distance, but I am impressed for sure. The daily driver is better than any of the tunes that came with the Hydra from factory. I’ll know more when I’m able to pull long distance and hills for sure.
Mitchel S.
Everything worked great and performed very well
Russell
Thank you to the Jelibuilt Performance team, the difference these tunes have made to our F250 are amazing!!! It has so much more power and torque we honestly can't believe that it is the same truck.
Cheers from Australia
Russell
Jacob N.
The tunes were great and the customer service was excellent
colby S.
Thanks guys. The tune you built for my e99 is amazing. Fixed my shift delay 2/3 due to over-sized tires. For a daily driver tune the response and power is far superior to even the high power tunes that came with my hydra.
I highly recommend this company.
Thanks again
Colby

Only way to explain how good Jelibuilt and the tunes are is to explain it slightly more detail. One of our fleet vehicles is a 2001 2 door 4x4 f250 super duty ZF6 that was purchased by us (a mining excavator maintenance company in Australia) from the 2nd owner with a replacement engine 99 spec but due to poor maintenance practices the new engine had been dusted so compression is not the best but aside from ring wear it’s ok for now but it will be rebuilt at some stage in the near future when we get the time. We have put another 140,000km on it while dumping every modification possible into it aside from internal rotating assembly, simply for reliability and decent drivability.
Without the Jelibuilt tunes everything else is worthless in my opinion it has exceptional drivability, idle, smooth linear power, maximum power tune is an absolute animal as the truck weighs 5ton rather than tyres it easily spins the clutch only rated to 1300nm. We could not be happier with jelibuilt tunes absolutely exceptional fueling at the exact moment it is needed. I can guarantee our company will only source fseries performance products and tunes from jelibuilt.
Matt F.
I had the stock hydra tunes and the drivability on the custom tune is night and day. The transmission shifts faster and smoother the TCC lockup on the stock hydra was sloppy. The custom tune is again night and day difference.
Morgan R.
I was having issues with the tunes I was running. The tunes would make the trans seem like it was slipping until I put it on the stock tune. However the JellyBuilt tune fixed my issue.
Kanden C.
Great tunes! and great customer service as usual!
Andrew D.
Good tunes, nice power,low smoke .
Smooth idle
Chase H.
Absolutely night and day difference in the hydra titan unlock and custom tunes on 250/100s. Throttle response and power is substantially better. Trans shifts so crisp and smooth now.
Justin G.
Had them write a tune for my work stock pulling truck with custom rpm and other things and it hits everyrhing perfectly. Highly recommend and will be using from here on out
Jordan B.
Huge difference. Even with stock injectectors, the jelibuilt tunes made an incredible difference. I get better power everywhere. Turbo lights up faster. Better egts, shifting, and all around drivability all while increasing my fuel mileage as well.
Jason A.
7.3 KC Turbos 1.5 kit and BTS tranny.
After two other tuners tunes, FINALLY some that perform flawless! My 3-4 shift in the BTS tranny was sloppy until I got the Jelibuilt tunes. 10/10
Thomas G.
Great costumer service
Alfred G.
Very last minute issue came up. Had to put AD injectors in my stock OBS. Called to see if jelibuilt would write a tune for my situation, with a failing transmission, and was told up front not to expect much out of it. Went ahead and ordered the tune, could not have asked for anything better up front. Need to “data log” my Hpop values during start up, to see if long startup is from anything else failing. Will definitely be calling back to get updated tunes as soon as I get my parts together for “upgrades.”
Marcus C.
Customer was very happy with tune. Paired with KC stage 1 and FF stg 1 injectors the truck drove perfect wioth almost no smoke. EGT's were perfect and throttle response was on point. Great job Jeli!
Craig C.
I’m loving it!! Love your tunes and you will be recommend by me!
Brady A.
Transmission tuning was spot on. Performed as expected. Very pleased with the purchase
Nick K.
The team at jelibuilt is top notch. I needed some additional tuning, and they hopped right on it! I had my tunes that afternoon and had my issues fixed same day! The truck runs fantastic and pulls like a freight train now. I can’t recommend the tuning and the company enough!!
Richard B.
Submitted my purchase order for Tunes in the morning and received an email that afternoon with my tunes, wow that was fast! Best tunes on the market for 7.3
Thank you, Richard
Bruce C.
Great customer service will recommend.
Fleet W.
Great. Power sounds quiet all good
Dylan A.
Love the tunes. Runs and shifts great
Michael
JeliBuilt has the BEST tunes out there !!!
I have tried multiple tunes and Brian’s are the best by leaps and bounds !!!
Jake G.
Awesome tuning super smooth decently clean fast revision’s.
Jacob
Fast shipping with great tunes.
Jonathan G.
Bought 2 custom tunes and received the files in an hour!
Benjamin M.
Bought and received same day, very easy to contact with the questions I had. Tunes worked perfectly from the start. Overall a great experience.
Troy W.
I switched to Jelibuilt when I redid my injectors and turbo. I knew there would be a huge difference but I didn’t think the biggest change would be the tuning. The transmission is smooth again and the truck runs amazing.
Anthony T.
Runs smoother, quieter, shifts smoother , throttle is more faster to respond all around a better running truck. Before the custom tune when trying to pass vehicles it would try to ‘hunt’ for the right gear. Not any more it stays in the power band. EGTs also drop about 100 degrees . Should have gotten these tunes years ago - am running stock injectors and I made a huge difference.
Jason W.
VERY QUICK AND AWESOME
omar e.
Quick and awesome service. Tunes are as expected. Will be returning. Recommended for everyone looking for great service and knowledgeable pros.
William B.
Had zero problems with the tunes. When I had questions there was no dumb question or answer. Will continue to get my tunes from! Thanks keep up the great work
Kevin M.
Awesome customer service. They looked at what i needed, and wrote me a great tune that knocks the pants off anything we have ever had. We run a fleet of 7.3L trucks, we will keep using these awesome tunes
Matt A.
Bought a used 7.3 with a bigger turbo, bigger injectors, and a 6 position chip. Everything sounded over worked and strained.
These custom tunes from Jeli are a night and day difference! Couldn’t be happier!
Russell E.
Made a world of a difference to the truck, without making it drive rough, would definitely recommend to anyone looking for a solid power boost for there 7.3, or 6.0
Javier J.
Great Experience, Tune is working great.
Gary W.
Top notch parts and service!
trayton f.
Runs much smoother. Throttle sensitivity is much! Smoother idle all around 100% better tunes then Previous custom tunes I had
Shane M.
I bought 4 new tunes for my truck. It runs great now with my T4 366sxe and built trans. I’ll be coming back once I upgrade the injectors when the time comes. Thank you Jelibuilt!!
Zach S.
Saved a lot of money on fuel usage and when u want her to rip she takes off like a bullet and runs super smooth
Mitch B.
very easy to download and upload the files onto my Hydra, much better tunes than other companies i have tried to use and needed to revisions.
Brent G.
I was after a low smoke tune and it worked perfectly.
