Power up - Gas down

Noticeable increase in HP and firmer shifting at higher RPMs. Lost MPG in city & HWY which was disappointing. '14 Silverado w 6.2L

Love It !

Reviewed By Brant M (Houston, AR) Reviewed for a 2013 Ford F-150 —1/15/2015 10:51 AM

I have a 2013 F150 STX 4x4 with a 302. I like the way this thing works. I set it up on the middle setting that increases up to 25 HP. It was pretty quick before but now it screams. My truck shifts better than having the tow-haul button on. My gas mileage is 3 mpg better all the time and some nice flat roads it's doing 5 mpg better. This tuner along with my K&N cold air intake has woke up that 302! Can't wait to put on dual exhaust to finish the performance job on my 4x4.
