We found 4 holes in the trunk and the previous owners name is bottlefed93. He said the car had nitrous on it but it was never used, I find that hard to believe since the car has 30# injectors in it. My guess is it had to be sprayed with a BIG shot to need that much fuel. The MAF is a stock Ford MAF, it could be modified but I dont think so. My Pro M MAF has injector size and ECU code engraved in the top of it, I would think other companies would have something similar.
