Its there to use or not, I don't care. I explained what pissed me off, the attack on my credibility and the stupidity of the moron(s) claiming engine damage. That's (IMPOSSIBLE) from this mod. But hey, why do YOU have to rant at me? Just IGNORE IT (and me)! Have a nice day. This is a UNFORTUNATE all too common problem on the net, sophomoric and uninformed people ganging up on someone offering help (for FREE, by the way)!! Whatever, Brad. I am not the one wrong, and trying to BS someone! Ignore it, as stated already...unless someone is "PISSING ON YOUR PARADE" and you're upset, hehe. Then, attack someone who cares about what someone who knows that little about engine dynamics they'd state something OBVIOUS wrong, then defend it! This truck (like all my other 8 I owned like it or similar, ALL responded as this one, very well...Its just the STUPIDITY of fools who buy a CAI, but then leave HOT water making the CAI ineffective!! Sheesh!
