Yeah, its a 2004 WRX 2.0 with an 18g. It has a SPT Intake and fmic sti pinks (Those are coming off needs bigger) exhaust headers .
I've personally cleaned the MAF on more then 1 occasion. I'm going to swap mafs friday and see if the problem follows from his car to mine. Other then when the MAf Flakes out the car pulls like a raped ape.
The problem has been happening on and off for a while. The car has been down for a bit because he blew a gasket in his headers and had to have IPS put a Flange in and weld it.
IPS did a BL test before the car came out of the shop. I had the car for the weekend a few weeks ago and it seemed like to me the car was reading entirely to much air for its build. I'll try and get some datalogs off the car with the MAf voltage.
