DiabloSport 8400 inTune i3

This is a great tuner for stock cars. I have a 2010 Jeep Grand Cherokee S Limited with the 5.7. I downloaded the latest software through its WiFi with no problems and put the 91 octane Diablo tune on it. It really woke up this engine up! I change the throttle to 20% and all the shift points to 6400 RPM. I might go back to 5800 or 6000. The transmission is silky smooth now and I can squeak all for tires when I jump on it off the line. I’m getting a little bite more mpg but the power is now right there waiting for you. For 400 bucks and no other up grades this some what cheap looking tuner really helps all around drive performance. I have 10000 on it and the 0-60 times are better then when it was new I’m now in the low 6 second range.

That's what it read when I attempted to use.

My 2012 GC WK2 5.7 hemi, came from factory with midgrade tune. Unit says 93 Diablo tune not available for truck(not in California). And if returned lose $$$. Best customer support on planet Earth! After contacted, they sent 93 octane tune and truck now is BEAST! BTW Turns off MDS system and very customizable. Highly recommend

If you are debating if wether you should buy it or not do it so worth it i can do burn outs now and idk about the saving gas but who cares my jeep is on 35 and on a 3 inch lift and it is relly hevy and it gowes more than 100!!!

Didnt work for my jeep wrangler, but had advertised as such. Call to verify functionality
