If I install a Pro-M for 19lb injector, will I gain a significant power? My car now has stock meter, edelbrock upper and lower, powerheads, saleen headers, borla exhaust, pulleys, 190lph, 3.55 gears.
Its not a Pro-M, but when I installed my C&L 76mm I was very impressed with the power gains! I had similar mods to you at the time. I would also make or buy a CAI while your at it, so the air intake is opened up to take advantage of the bigger MAF.
If you want to spend some money you can install an AFM PowerPipe with a shorty 80mm MAF and gain a good 7-10rwhp. Just swapping in a MAF alone will not help that much unless your car is running rich/lean and the meter happens to cure that.
Where is a good place to purchase the 80mm Pro M? Should I order the one for the 87-93 or 94-95? Also, do they make a shorty (blow-thru) design? Thanks.
