newbie question. 09 xr6t manual. interested in a growler, big mouth, and (after reading this thread) a high-flo cat. obviously, an x3 tuner as well. would like a little extra oomph, an more interested in intake noise, not exhaust noise, hence the intake mods and only getting a cat. the question is, can these parts be added on at a time, and then get the tuner on it later to realy make the most of it all? read in here the ecu will self adjust after 500kms to suit the improved induction/exhaust. yay/nay? also, standard BOV is a plumback. have removed the pipe that joins the BOV to the intake, and blocked the hole left in the intake (as it was post filter) with a large heater hose block off, and the OEM clamp. the BOV now exhausts straight out into nothing. gets a nice nittle pssstchhh noise. regular thing to do?
