I dropped it off Monday a.m. and got it truck back yesterday afternoon! Not bad. I have got to put my chip and filter back on, and take her for a spin. Can't tell if it feels any stronger or not with the stock air box (as some people are saying theirs feel stronger after the replacement). This was NOT an SVT dealer, btw, as the one here will not get any more of my business. Just thought I would relay the message that this was much less painful than I anticipated.
