Customer Reviews
Awesome Performance, Easy Tune Revisions
Hey everyone, just wanted to share my experience with JeliBuilt Performance. I picked up one of their cold air Intake Systems a while back and was really impressed. Recently, I needed a tune revision for my Towing Tunes and was wondering, how do I request a tune revision from JeliBuilt? Turns out it's super easy, just shot them an email and got a response back in under 24 hours. They had the updated tune to me by the next day, which is way faster than some of the other places Ive used like 5-Star Tuning. Definitely recommend them if youre looking for quality parts and quick support.
Got my Daily Driver Tune
I bought a Daily Driver Tune for my 6.7L Powerstroke a couple weeks ago. It downloaded pretty easy onto my tuner, and I noticed the difference right away. Truck feels a lot snappier, especially on the highway. Good stuff.
Good experience with Hydra tunes
I ordered a multi-tune package for my 7.3L Powerstroke, specifically the Hydra Chip Custom Tunes. The ordering process was straightforward on their website, no hiccups there. I got an email pretty quickly after purchase with instructions on how to download everything, which was nice. Loading the tunes onto my PHP Hydra Chip was pretty simple following their guide, took maybe 15-20 minutes total. I've been running the Towing Tune mostly, and it's made a noticeable difference when pulling my trailer. Engine sounds happier and definitely has more grunt. I also tried the Extreme Street Tune for a bit, and while fun, I stick to the daily driver or tow for most things. Overall, the quality of the tunes seems solid, and I haven't had any issues. Support wasn't needed, everything worked as expected.
Fast tune revision
Needed a revision for my 6.0L Powerstroke tune after some injector upgrades. Sent in the request and got the updated file back in a couple days. Installed it, and the truck runs much better now. Quick and easy.

Anyone know if JeliBuilt is legit? Found some good deals but wanna make sure it's not some rando doing tunes.
Do these guys ever do sales? I'm looking for a Hydra chip bundle but trying to catch a deal if possible.
Thinking of picking up a Hydra chip with some custom tunes. How long does it usually take to get them after ordering? I'm in Texas.
I'm running bigger injectors on my 7.3. Will JeliBuilt tunes work with that or do I need something special?
Hey, I'm trying to decide between JeliBuilt and Tyrant Diesel for my 6.7. Any experience with both or strong opinions on who's better for daily driving and occasional towing?
