The factory MAF is a 55MM housing, smaller and more restrictive than the 60MM throttle body housing. There is probably some performance increase there using a MAF w/ larger diameter. Not familiar with the Venom system. It looks like a MAF signal modifier that is useful for tailoring MAF transfer rates and fuel curve and probably would still work with whatever size larger MAF you go with. I run a 73MM C&L with the cal tubes to adjust for injector size. It get's the curve in the ballpark and I adjust my A/F curve with my programmer from there.
