If you already have a DiabloSport tuner and want to get your tune a little more tailored to your Dodge, Chrysler, or Jeep vehicle, this is the option for you. This is for stock to bolt-on modifications. We will make provisions for throttle body's, CAI, and exhaust/headers. For many preloaded tunes there's a lot more left on the table over the preloaded tune files. Email us your last tune written and/or backup file and we will email our tunes back. Send us a datalog and we will tweak the tune as necessary. This ensures optimum performance of your current configuration.

Reviewer: Joseph Mata from Hinesville , GA United States  
Heard of hemifever and decided to give them a shot. A lot of good things were said about them on forums, YouTube, and other sites...

Own a 2016 Durango AWD with an intake, headers, exhaust, and 180 t-stat. Ran the canned 93 for a while until i decided to give Sean and hemifever a shot. it was a decision, well made. the custom tune pried out a little more hp and definitely improved shifting points. all said and done, my  5400lb monster gets up and moves. tested the 60 and 1/4 mile times on my trinity and the numbers were very similar to an R/T charger which weighs 1100lbs less.

two thumbs up!!!

Worth the money! January 25, 2018
Reviewer: Jesse Bequette from Byers, CO United States  
Purchased the diablo tuner for my Ram 1500 and purchased the Stage 1 Hemifever tune.  I ran the canned tunes for a few days before downloading the hemifever tune just so I could get a gauge on difference.  The hemifever tune made a HUGE difference over the canned tune and an added bonus was my MPG improving as well.  I highly recommend this tune and have already purchased the transmission tune as a result of my experience.

Worth every penny! July 7, 2017
Reviewer: Joey Arch from Charlotte, NC United States  
Purchased a Diablosport tuner and tried out the canned tunes. Honestly, was pretty disappointed in the 93 tune. For the money it did not seem to make much of a change. Reached out to Sean at Hemifever and got the 87 and 93 tunes. Both were way better than the canned ones. The 93 especially did the trick. 300c 5.7l is no longer sluggish. Its officially a luxury barge muscle car. The customer service provided was some of the best I ever had. He has a customer for life.

Hemi Fever Beast November 24, 2016
Reviewer: Alan Williams from Evans, GA United States  
I bought the Diablo Tune and I could tell a difference in my 5.7 hemi but then I bought the Hemi Fever tune from Sean and he sent me the file and I uploaded it up to my car. Well Let me tell you My torque and horsepower has increased tremendously without popping the hood. I am totally pleased with my tune Sean works with you and communicates with you so that you understand what your motor is doing and what parameters he changes to get the best from your motor without changing one part pretty awesome I am truly pleased and can tell you that if you want budget performance this is the way to go best bang for the buck.

Stage 1 Tune June 20, 2016
Reviewer: WAYNE WALKER from CINCINNATI, OH United States  
My Charger 5.7l was slightly modified with custom Air Intake and Cat Back Exhaust. It was cool but just not enough for me. After working with Sean  I really feel the  power his custom tune made. Sean was patient and easy to work with. He also made a suggestion on how I could get more power. Right now it's hard to not burn rubber on take off, before it was hard to burn. Definitely a noticeable difference in power and shift points that Dodge doesn't want you to know about. Before my custom tune from Sean I found it hard to reach 130 mph,(Dodge sets a 130 mph governor in the computer). With Diablo Tune this can be removed. Once this is done the custom tune is surprisingly powerful.
Great job Sean!!!
