70mm Throttle Body
 

Would there be any advantage to switching to a 70mm TB? I thought I read somewhere that gains would be minimal but I can't remember for sure. Would I see any extra gains because my exhaust is freed up a bit and I plan on adding a WMS Velocity Tube w/ 87mm MAF? Thanks for the help.
