High hopes

Reviewed By Will B (HUBBARD, OR) Reviewed for a 2011 Jeep Grand Cherokee —2/7/2016 5:57 PM

Read that works best if used with premium fuel, have ran premium in it the whole time I've owned my jeep. It does actually work as advertised. More power across entire RPM range, has increased my mpg by only 2 though nut still an improvement.

Not sure, but I'm happy

Reviewed By Tony C (Carolina, PR) Reviewed for a 2011 Jeep Grand Cherokee —2/26/2015 1:38 PM

I hated the pick up on my 2011 Jeep Grand Cherokee Overland, and can attest that after I plugged in the Tuner I definitely felt much more "pep" when I step on the gas. However, my MPG has gone to crap. I think on highway I do get better mileage now, but in city I get worse, and I drive mostly in the city. Someone who puts mostly highway miles should see an improvement. Either way, it made me much happier to drive my car, and that is worth the 300 bucks to me.

Nice addition to 6.4 SRT8 Jeep

Reviewed By James F (BINGHAMTON, NY) Reviewed for a 2012 Jeep Grand Cherokee —5/10/2017 8:43 PM

Awesome little power pack! Very user friendly and easy to do. Not just more power at WOT but tighter shifts and better with just moderate throttle increases. Clears the annoying back pressure codes that come up with an after market exhaust. Noticeable difference for not much out of pocket and nice addition to intake and exhaust upgrades on this 6.4 SRT8 Jeep.
