[QUOTE="robert presti, post: 15288501, member: 175530"] The car was blow through both times and in the same (not so ideal spot) in the wheel well. The car has never been vented to the atmosphere so to say, it recirculates back to the front of the supercharger. I believe this is this way because at one time it was draw through. No changes were made to the pulleys. I can watch the AD counts fluctuate by as much as 100 when the rpm is over 1200 and the throttle is nearly closed. I could be wrong but it seemed with the past MAF it was something like 20. Seemed much more stable on afr than now, but hysteresis coasting fuel cutoffs might have been set much higher. I'm going to bump the rpm limit there and try to get a screen before the MAF, to see if I get back to where I started. I might move the MAF closer to the engine in a better spot as well, but I'd rather not see it. [/QUOTE]
