I was a little worried at first with some of the negative reviews, but I haven't had any issues. It does what it's supposed to do. My truck doesn't feel like it can't pick a gear any more which is great! Didn't notice any gain or drop in mpgs. Also works on my 2011 Yukon with no issues. It's a great product for the price and would recommend it for any truck with afm.
Didn't want to look like every other mom. Put 2.5 level kit with 33x12.50x20 mt's. Shifted like crap b4 the Predator. Shifts great,and noticeable performance.
