The boy loves his tunes
Store owner replied: Thanks for the review! Love the regular cab and hood stack!
Truck runs great with jelibuilt tunes
Brian is the man when it comes to tuning these ol dinosaurs. I recommend his tunes to everyone that comes to my shop and online I talk to.
Jelibuilt brought my old 7.3 back to life, have a bigger turbo and injectors but the tuning is what makes everything work!!
Run good a lot better more power than the ts chip I had in before. Great tune
I had some shifting problems and running issues and Brian fixed me up. I worked a few bugs out and now she’s running great and shifting like it should. 4 years in the making of having a cool built 7.3 obs truck. Thank you guys!!
I logged 764,000 miles on my 1998 E350 diesel before replacing the original injectors with Full Force Stage 1 with a Hydra chip and six tunes (stock/high idle/light tow/heavy tow/performance street/ext. performance). The van was transformed from it's original performance. After re-learning how to drive it using the tunes provided, I realized the light tow tune that I used most often was not optimal. It would shift into OD at 48 mph which is way too slow. Especially when trying to merge onto an interstate. Reached out to Brian to see if this tune could be changed to correct this situation. He sent me new light tow and heavy tow tunes to my email that I could load myself to the Hydra. The result was astonishing! His revisions are unbelievably better and make the van an absolute joy to drive. Shifting is smooth and exactly as it should be up through the gears. I only wish I had contacted Brian sooner! Proper tuning is essential for driving safety and enjoyment. Brian is a wizard at perfecting tunes. Making adjustments is easy if you install the remote data cable to the Hydra during install. Simply connect that cable to your computer and download any revisions you need. It's that simple. Can't thank Brian enough for how wonderful my van is to drive now. Simply the best! -Karl
Great clean tunes!
They always reply to my questions with great advice.
You never fail to have quick, accurate and transparent service!
Store owner replied: Thanks for the 5 stars, Kelsey! We appreciate your support!
Helped get my transmission dialed in! Super happy!!
Haven’t downloaded the tunes yet but one of the best customers services I have encountered! Thanks for fueling the diesel community
Truck runs Awesome highly recommended
I had put a new kc300x stage 1 gen 3 turbo on it and there was more to be had (truck already had 200/30's). I got revisions for it, then the next week took the truck on a 3,000 mile trip - towing a trailer, around the SW of the United States. The power as well as drivability and powerband is all I could ask for. The truck now drives like a new 6.7 (in my mind) has plenty of power and runs as it should. Not once did I have to worry about it. I don't see anyway that the truck could drive any better than it is now.
Brian was quick and the tunes are awesome!
Tunes were easy to load and the truck runs great!
Revisions fixed all my issues with the manual swap and larger injectors. Runs great now.
Amazing customer service
Im fairly novice when it comes to adding tunes and this sort of this. My wife got a laptop set up for me to use in the shop, I opened u our email and was done putting tunes in my truck in less than 30 minutes. Took me longer to pull the interior panel to get at my cable. I'll be buying more tunes in thw near future
I’ve had their tunes for several years now I needed an adjustment because I put a new transmission in the truck. I simply made a phone call told him the upgrades I had made and new tunes were in my email within 24 hours. Truck drives like a dream.
You want great tunes? Get them from JeliBuilt Performance, best tunes on the market. Also great customer service on revisions!
I upgraded to a John Woods valve body and with the stock transmission tunes didn’t feel a difference- the tune revisions firmed up the shifts a bit and it feels like more power is getting to the ground.
I asked for tunes to pull my toy hauler. Got two right away and can now pull up our grades. Thank you JeliBuilt!
Tunes work well lots of power in the hot tunes and Cool EGT’s plus good power in the tow tune
Tunes are great
Never an issue. Always great customer service.
Brian and Kathryn are the best!
Sales was VERY helpful, even just over email.
Simple install/upload, great customer service would recommed
I have a few more videos to share this is my hot street.
Hands down jelibuilt has the best customer service out there. I’ve delt with several other diesel performance places and not 1 comes close to the service/helpfulness of the staff at jelibuilt. Will always do business with them when I can!
I upgraded some parts and switched to single shot injectors. Talked to jelibuilt and had them do a tune revision. Downloaded hydra flash plugged into the usb and deleted old tunes, uploaded new tunes super easy and fast. I’m not a computer savvy guy and it was all super easy. The throttle response is immediate and so far the tunes feel great. Only had a night to drive it with the new tunes. Super happy for the ease of adding new tunes.
Fast and responsive! Best tunes on the market.
Every time I use, you guys are awesome 😎
10/10 quality service
Always very helpful. Tunes are great! Would definitely recommend
Always knowledgeable and great customer service
The tune worked, the truck turned on and idled perfect
When my transmission was rebuilt by the previous owner, some changes were made that resulted in harsh torque converter lockup. The associate that I worked with was very patient and helpful. The whole process took a few months due to other mechanical issues that were uncovered through with the suggestions I was given. It was just amazing experience. Thanks
The tunes I got are great and the couple of times I reached out with questions, the customer service was outstanding. Thank you, again.
