I have the intake freed up, the full exhaust has been done. Next plan is the P&P and I talked to the guy who dynod my car, he said the CO is coming close to the normal, which means A/F ratio is coming to stoich. And when I do the P&P , I just don't want to take the risk running it lean. So just in case I would need the FPR, when I have to add some fuel.
