Uninstall and reinstall. Try it again. It only takes a few minutes. Then report back. The ap should clear all cels. What was then cel code?

What is the specific question you want answered? Any more info?

Clean maf sensor
are you getting full boost? How many psi
and you did flash the ecu with the 91 map?

Put the stock intake back on, for starters. If you're not tuned for the intake, you could potentially cause fuel trim problems and cause your car to run poorly. Most cause alot of turbulence at the MAF sensor and cause all types of erratic engine behavior. Even if you are tuned, the short-ram intakes are universally bad (unless you have a properly set up intake heat shield), as they suck in hot underhood air, causing your IAT to be abnormally high (that's bad- your ECU will pull timing when it sees high IAT). There's a reason people refer to short-ram intakes as "hot air intakes".

if everything else sudjested in this thread checks out fine. you might want to look into replacing your fuel pump. i think you can monitor the air fuel ratio with the accessport and even tho its a narrow band, you will still see it runing around the 14ish area at WOT if the fuel pump was takin a dump. Had this same issue with a buddys car that looked like it was a bad maf since it ran fine after swapping mafs, but the problem returned
