Just got off the phone with SHM tech support. this guy, (contrary to Chris in the sales dept.), told me to expect between 310-330rwhp with my setup. He said the odd thing in my case was the fact that the A/F mix was 11.4 (as they usually run 13:1 on their cars) and that my torque was lower than my HP (usually about even). he suggested getting a compression test and a 'leak down' test. i have never heard of a leakdown. can anyone inform me?
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.
