BAMM: Big Ass Modshack Maf Mod

rss

According to calculated ID differences with the stock MAF housing, this should flow 10% more air. Velocity will be lower and reduce G/Sec readings proportionately, but use of 4 bar FPR seems to bring everything back into line nicely. Driveability, low end grunt and tip in power all seem to improve nicely. It is a mod you can definitely feel. All Fuel issues are now in line with the FPR. No cels, and within 4-6% of 0 adaptation levels! Write-up here:

A 4 bar FPR Bosch # 0 280 160 575 is necessary for this mod (2001 Passat 20v)
