Hypertech Interceptor Tuner Reviews


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.

2005 WK

Reviewed By Tim R (LAS VEGAS, NV) Reviewed for a 2005 Jeep Grand Cherokee —2/21/2013 8:24 PM

Bought to recalibrate speedometer to improve mileage, trans shift at correct RPMs, and accuracy back to stock-- it did this exactly as product was described. Very effective, very easy to use which is a big plus!
