If you have aftermarket tuning, it's based on the injector that you are running so a tuned MAF would not really be needed. If the MAF coming out was setup for 24lbs, the tune shouldn't need any changes at all. If it wasn't, there is a possibility that a re-tune could better optimize, but the change would be minimal if anything. That being said, my white car was on 24lbs injectors and stock ECU/tuning and it ran the same on a stock MAF and two separate tuned MAFs as I was trying to solve a rich issue and neither seemed to make any real difference. Also, I'm not sure where you got a Delphi MAF that's tuned - Delphi makes OE replacement parts, not performance variants. PMAS and maybe BBK were the general go-to back in the day.</p></blockquote><p></p>
