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.

Hypertech Max Energy Programmer Reviews


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.

A cost extensive and striking tune up.

Reviewed By Axel H (SARASOTA, FL) Reviewed for a 1994 Jeep Grand Cherokee —11/18/2014 2:05 AM

I bougt this unit for my stock Grand Chereokee `94. It is easy to install, I only had to pick out the can for the coolant. The electronic and engine is in a better balance and more straight than before. For this price, this is an unbeatable tune up.
