Now, how would a tune affect the graph? Would a tune bring the torque and hp up, stretch it out, lower it, what and how??? This is the question.

i dont like the fact you lose so much torque off the line. but if its the sound you like, then go for it.

I designed the muffler to be free flow but because of the temp drop of the exhaust gas in mid car, we changed the diameter of the tubing to bring the velocity back up. We're one of the few companies to make a muffler designed for each application to do exactly what you talked about in your previous posts. Good observation!

tune what? the computer? bmw engines already run at near max potential, unless you have a turbo....
of course the computer, on the car. hello, have you not seen the posts regarding SINGH, PES, ESS, etc tunes? come on, if you're not into at least the possibility of tuning the car then why are you looking in the Parts, Accessories and MODS section to begin with?
OK, I'll continue my own search. Sorry if I disturbed you turbowad.
