well, hooking up the turbo and all, and i just had a thought, Im only running a small downpipe with the wideband and o2 in it to go to the dyno and tune shop, Then I'll eventually drive it to work where i can make my own welds and bends to complete the exhaust.
My question is with such a short testpipe (probably only going to where the cat is on the stock application/ just enough for the o2s) would the closness to the open atmosphere have any affect on the way the wideband will read??? I know exhaust gases are coming out- the pipe, but it's something that bothered me all day at work. I'd hate to run lean and blow my engine cause of a question i didn't want to ask.
