hmm with my mods i would say it definately pulls me back in my seat. and your mods are similiar to mine just more dangerous because you don't have supporting mods. If your sig is correct and your running a 2.8 pulley on a stock computer with stock plugs and wires you better start saving for a new motor. If you do get a dyno tune let us know how much of a difference you notice. At least I'm interested.
