There is no 2007 G37 coupe

Thanks for being so pedantic!

I think most know that the G37 isn't a 2007 model, so I never bothered clarifying.

stick with the 5/16; you will have performance increases over a wider range of the power band.

Also you the Cosworth is nice, but i would only get it if I was going F.I. (Turbo or Supercharger). The HP/TQ gains for N/A are similar to the 5/16" and
MREV2.

Yea, I heard the Cosworth are supposed to be pretty damn good with FI but the backorder SUCKS(so does the price but you can't complain)!

It’s absolutely not worth dumping the 1/2" and getting 5/16" - It is HIGHLY doubtful that you would feel the difference. Since you already have the 1/2" stick with it. I run 1/2" and have zero reason or need to get a 5/16" instead...

Is there a better upper plenum such as the APS tall boy or something that might work better with the MREV2?
