I went from stock MAF with GT40p heads, trickflow intake, heades, stock injectors , 3.73 gears etc and then added a 73mm maf meter. It was night and day difference. Think about it, you are going from 60mm to 73mm , thats 18% more air. The stock air meter is the main reason going from 88 to 89 years, the 88 was faster because it didnt have the tiny MAF meter inbetween the TB and filter.
thats what I thought too...more air the better, but mabey I should be changing my intake and heads before I even touch the MAF.
The amature that I am I put 70mm tb on without the egr spacer so It's not really doing anything at all. Didn't feel a thing but I guess I wouldnt.Im learning with trial and error and thanks to people like ghostdog and the rest of you on this forum, Its helping me learn with a lot less error...thanx everyone!!!
