Not sure, but I'm happy

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.
Unleashed the POWER of my 2012 Silverado 1500 4wd!!!

plug and play...this tuner literally unleahed the beast in my Silverado. I deleted the AFM system, set shift firmness to 50%, and tires set to 35"!! She RIPS down the road now. No irregular shift going downhill!!! THE MOST IMPORTANT is my MPG went from a dead on 11.5MPG to 15MPG. ALL is perfect now!!! BUY ONE< YOU WONT REGRET IT!!!!!!!!!
