DiabloSport inTune I-1000 Tuner Reviews


Excellent tuner for HEMI vehicles

Reviewed By Michael S (Allison Park, PA) Reviewed for a 2009 Jeep Grand Cherokee —3/23/2012 6:30 AM

Diablosport is the handheld tune of choice for HEMI vehicles based on info I learned from various forums. I'm currently using it on my 2009 Jeep SRT8. If you have a CAI and run 93 octane gas then the best canned tune is actually the 91 CAI tune. You'll get too much knock with the 93 CAI tune. Also, crank up throttle boost to the max 20%. My SRT8 is running like a beast! Top of second gear pulls like a freight train and the shifts are nice and firm. Best feature of the inTune is that you can data log and send the files to a tuner who works at Diabosport who will email you back a truly custom tune for a nominal fee.

New to me...

Reviewed By Henry K (Spring, TX) Reviewed for a 2009 Jeep Grand Cherokee —2/2/2010 6:38 AM

But as I have purchased Superchips models before to use on my Fords I had no problem using the Hypertech model on my Jeep Grand Cherokee Overland Hemi. Ease of use is always a strong point with me. My Hemi Jeep now runs the way I want it to and I am very pleased I made this purchase.

Tuning experience...

Reviewed By Henry K (Spring, TX) Reviewed for a 2009 Jeep Grand Cherokee —7/3/2007 6:56 AM

So far I have only tried the performance tune for premium fuel and am satisfied with the results. I would have liked a 93 octane tune better than the 91 but all is well with my 4.0L Mustang as compared to the factory tune. The tuning time was very short and difficulty factor was very simple. Even a caveman can do it.
