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 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.

5 of 5 Stage 1 custom tuning August 15, 2020
Reviewer: Nick Redmond from SC United States  
Had Sean do me a custom tune for my 2012 ram 1500 4x4 and it is a night and day difference from the diablo canned tunes! And the customer service is beyond my expectations! Sean worked with me after hours on a Friday to work out the details and make me a tune for my truck! I highly recommend the tune and doing business here!

5 of 5 Incredible Tune July 17, 2020
Reviewer: Brian B from Kansas, United States  
I was running the DiabloSport 91 Octane canned tune and it was working well, but I felt there was more performance to be had, especially with my engine modifications.  Sean did a fantastic job and made my car feel completely different!  With the HemiFever tune, I am seeing a 0.3-0.5 second reduction in my 0-60 times!  I'm sure this will translate well to drag strip performance as well!  I highly recommend it, especially if you have bolt-on mods!

5 of 5 Bought the I3 and the custom tune together. May 17, 2020
Reviewer: Greg Estrada from Long Beach, CA United States  
I got the i3 tuner and the custom tune together good price. Well lets just say its night and day don't know how accurate the SRT pages are but the hp has read up to 428 hp.  I'm going to see if I can get a re tune to be more jumping of the line. I have 14 RT

5 of 5 Best Tune Ever! March 27, 2020
Reviewer: Luis I from San Antonio , TX United States  
I got a diablo sport tuner and I've had a custom tune done by another tuner, and I just have to say that Sean knows exactly what he is doing. I fell in love with my car all over again, must get his tune 100% worth it.

5 of 5 Pretty impressed with the difference!! October 11, 2019
Reviewer: LT from Ocean, NJ United States  
Well let me start by saying I don't write reviews.   Ever.  Had to show some love for Sean and Hemifever Tuning.  If you are on the ledge and not sure, take that leap and get this tune for your hemi.  My 300c felt like a tank.  Two updated custom tunes later and Holy @#$%!  What a difference.   Can't wait to drive to work tomorrow.   Who says that?  Like a new toy.  Sean is super cool and really good at getting your questions answered.   Thinking about the Pedal Commander now.  You know how it is.  Once you start...I'll be back after a few more mods for sure.
