Oakley, did you disable all your o2 sensor? Or how did you do the pass side with trick manifold being it has no bung

 

No I'm still running the front 02's. Rick puts the bank two oxygen sensor in the down pipe which I don't really like but it does seem to work. It doesn't have any problems keeping cruise and idle at stoich. If you look at the trims on the scanner, bank two always shows wacky high numbers (+10-13%) and bank one has to compensate. So it's not correct but the wideband does show lambda 1 in closed loop


^^ The S475/83 isn't too laggy on the street. I'm in full boost by 4400rpm if I remember correctly. I've never had a smaller turbo so I can't say for sure but I don't think I would like a turbo to spool any quicker than this one. I like being able to drive pretty much in N/A form while cruising and then unleash the beast when I want to.
