We do not disable emissions monitors. 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 Impressed with the tune April 23, 2021
Reviewer: Gary M from Mt. Morris, PA United States  
My co-worker told me about Sean's Hemifever tune and I recently purchased.  Sean knows what he is doing, he built an 89 octane tune that woke up my Hemi!

5 of 5 WOW December 30, 2020
Reviewer: Matt F from Michigan  
I was running a canned 87 tune (on 89 fuel) and Sean hooked me up with a proper 89 octane tune. What an amazing difference! I did a 0-80mph run today and it just glued me to my seat. He also checks your recorded logs afterwards to make sure everything is running properly. Also, I've only had the tune for 2 days and my MPG average has already gone up by .2. More power and better MPG, what more could you ask for?

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
