Not that I don't agree with you, but are you taking MAF size or TB size?billfisher said:Dude that MAF is killing you. I mean KILLING. too big without supercharging. think of it like the larger the less sensitive. I am not trying to be an expert. I went with 75 with trepidations. bigger is not better. no real way to overcome you are not going to have the volume of air that sensor needs N/A. sorry
trinity_gt said:The numbers seem...a bit...stock-like, despite your mods. My 02 GT made 228.5 to the wheels bone stock. Looking at your chart, I'm tempted to suspect you might have a mixture issue. Was the Diablo used to tune with the 87mm MAF installed?
In your sig your say "3.5 {inch} pipes" ... you mean tips, right? You don't have 3.5" pipes under the car, right?
The Pro-M MAF has a different tansfer curve than the stock MAF. You need to either have the Pro-M curve programmed into the tune, or use the stock MAF. I disagree that the MAF is too big, You just need the right curve.comatose said:As far as the MAF, I find it hard to believe that going from my stock 80mm MAF to an 87mm one could upset the engine so, or be too big without a supercharger. Could the MAF be faulty? If it was, wouldn't I notice other symptoms? The idle is absolutely perfect.
twogts4us - Why should I get rid of the MAF?
