thanks, when i tuned at SFP it was about 10 degrees warmer outside, he had horrible ventilation in the shop, and i was running a b16 intake manifold and a mugen header instead of the toda. you would think that putting the larger intake manifold on would lean the car out but who knows, somehow something got messed up because i have the old chart from SFP and the a/f was not where it was when i made the baseline at SS the other day. SFP had turned off my O2 sensor and had something else set up screwy so who knows, it definitely runs much better now and i john did an amazing job
