i am looking at getting a maft pro after reading that it could be a much better alternative to the lex afm and 550 upgrade for relatively the same price. are there any downside to the maft pro? I would need a wideband setup to run the maft pro too... what would be a good wideband setup that is cheap but gets the job done? My mods are: k&n fipk, 3 inch from turbo back, mbc, and hks ssqv. I hear that you can use the maft pro to run absolutly no maf with the speed density mode... are there any downsides to this? Anything else that i have completly forgot about needing? Thanks guys.
