"I FELT AN IMMEDIATE DIFFERENCE IN THE POWER MY GRAND CHEROKEE THE PASSING ON HIGHWAY ROADS WAS IMPRESSIVE. TO SOON TO TELL IF I GET BETTER GAS MILEAGE I WAS TO BUSY CHECKING ITS POWER." —Dominic P from Wallkill , NY bought a Hypertech Max Energy Programmer for a 2009 Jeep Grand Cherokee.
"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." —Henry K from Spring, TX bought a Superchips Flashpaq Tuner for a 2009 Jeep Grand Cherokee.
"I bought it because my vehicle was listed as supported but after updating it said that there was no file for my vehicle. After contacting superchips they said they will work on building me a file as well as calibrating it before releasing it to the public. We will see what happens and I will keep you guys posted. They are awesome people and have worked with me and kept me in the loop. They are writing me a file for crying out loud! 2009 jeep grand cherokee 5.7L Hemi" —Ashkan G from Houston, TX bought a Superchips Flashpaq Tuner for a 2009 Jeep Grand Cherokee, 5.7L Hemi.
"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." —Michael S from Allison Park, PA bought a DiabloSport inTune I-1000 Tuner for a 2009 Jeep Grand Cherokee, SRT-8, 6.1L Hemi.
