Ok so i just put a test pipe on my b6 1.8T...I will post a vid later, it sounds kinda wierd, but not really ricer..anaways, a friend of mine asked me if i got it tuned because he says i will be running lean/rich? Does anyone know if i actually am running lean/rich b/c I have my test pipe? THANK YOU

Edit: And my CE light came on after i bought a thing for the second o2 sensor..im gonna take it to auto zone and see the codes..im sure it has something to do w/ the TP.

bump

for the CEL there's a fix for it. search for it. there's a dude that did it and hasn't gotten a CEL for it. as for running rich or lean, cincytt can tell u a lot more.

im pretty sure the whole running lean/rich thing applies when you over doo the exauhst flow. like loosign back pressure by having to large or too much flow through your exaust. correct me though,but thats what i've read.

i put exhaust and TP before i got my chip (because i got a great deal)... it made the car spool up quicker and made it cool down quicker.... i can smell some unburned fuel when its idling in the garage but my correction factors stayed about the same
