This is all contrary to Chris (the sales guy), whose numbers were much larger when attempting to sell the product. go figure.

meanwhile, random question: i currently have 2 chamber flowmasters, would i see a difference if i switched catbacks to Magnaflow or Magnapack? lemme know what you think, what your experience is, if ya want.

Yes, your A/F is too rich. Since you are N/A you need to lean that thing out, which will give you some more HP. Your TQ/HP numers are a slight difference. On a 4V you never see monster TQ numbers like a 2V, and they are generally lower. What is your CR? As far as the heads, the B heads are holding you back a bit as well, contrary to what Mogs is saying. Stage one is very mild port. What is your cam profile? There could be many reasons involved.

Again, other than what a dyno is saying, how does the car feel to you when driving????
