I will say though you need to make sure that there is no intake leak, and that those oem o2 sensors are all good, also that the MAF is ok. But from memory you checked all that.

Well A. it's over a week and the codes have not come back. I only said that there may have been a leak..the car showed no symptoms at all of an air leak when i had those codes It did 140mph..it would not go that fast with an air leak.. I believe my sensors are ok..they tally with the readouts i get from emissions tests. The 160g / sec equals 24lbs a min of air..maf goes to 35lbs , no prob there then. The car runs OK now but only reaches 110. So.. it runs very smoothly, idles fine..but does need a tune/injector constant table update... I think what you said about open loop and closed loop running is proved by this. Personally i prefer to have to drive slowly for a while with the 19's than have the 17's and the risk of overheating and engine failiure when overtaking at high rev's in 3rd...G.
