I suspect it's the MAF since all other sensors' values are correct. I have MSDS headers, no cats and a single 3.5" muffler so it flows. There are also Autothority chips in it that were set up for this exhaust. The problem just started late last season and is slowly getting worse. Fuel pressure/volume is okay and is set properly and non-linear for the 42# injectors. The car was fine for 5 years and all of the sudden is getting the lean spot. I know that other style MAFs go out of cal and with 89K on the clock, this one is probably drifting. The other end of the fuel curve is okay...especially under boost.
