maf and throttle body diameter

[Speedster986]

JD,

Once I get a parts list together, I will be sure to forward it on to you.

I'm not far from completing that task, all I really need is to hear from a few the guys i.e. The Radium King, Homeboy981, AndyA6, etc.

I'm leaning towards a TB 74mm from a GT2 to replace my stock TB 68mm. But pulling the rest of the set up is still work in progress.

FYI - Since the my plenum upgrade in Nov. 2012, I have been averaging 23 City 37 Hwy.

Have you ever used the Porsche OBC to calculate MPG?

If so, what are your results?

Thanks!
