i have ppe and i think its junk. if i had to do over again i would buy ats just soley because i dont like anything ppe makes. mine has thrown the belt off 3 times. one time at over 100mph on the dragstrip and bent the bottom of my 750 dollar cowl hood. i have 2 friends that have done the exact same thing, and i have it shimmed, as do they( even though the instructions dont tell you nothing about it). oh and i have another buddy with a common rail dodge and it did the same thing. when i talked to dan, he pretty much called me a liar and a dumbass and said i didnt install it right. i have no use for him either.
