Sorry, do not mean to offend, I just do not see the ROI here. With all you have on you car you have spent I would have to guess at least $4,000 > and your 1/4 compared to mine last week are 3/4 of sec better (I ran 13.5, @ 105) and 3 miles faster, and my SRT-6 completely stock, with 20k miles on it. Now I say this, but I know in time I will do the same damn thing, and more, but I would think there is more bang for the buck somewhere! Question what will this do if you paid for extended warranty, is this voided with the Renntech solution?
