[QUOTE="exdeath, post: 8690576, member: 56343"] Divide and conquer. Looks like you already know where the problem is. Disconnect the MAFia and putt around a little and see what it does. (go back to a stock tune if you have to, just to use the stock MAF curve temporarily to test the MAF sensor without the MAFia) Borrow a MAF from another car if you can. Etc. Obviously don't go balls out with it or give it any boost until you've got it straightened out and flashed back to your current tune with all those mods. If the MAF reporting low, you're running lean (more air than the computer can see due to low input), so it's running better when it's cold from the extra enrichment which compensates to some extent. If you logged fuel pressure from the rail PID, not just a custom gauge, then that is the FRPS and it sounds fine. [/QUOTE]
