TRU!

So your saying that the ZZP stage 2 throttle body comes with no MAF screen straight from ZZP that way?
Yup.

Yup.
I can see how the opened up TB would help with turbulence.

My 98 idles somewhere in the 8-900 range (no numbers that low on tach) with the gutted box and no screen.

The GTP idles at 680rpms (according to the Autotap) with no screen, and the SSEi idles somewhere in the 800 range with no screen and stock throttle body, but that is probably because it still has the stock airbox. Never had any SES lights because of no screen in either car.
