I have a ZZP one but I cant remember if it is on my car now or if there is a 2.8 on there now.
I will look and let you know.

I do know I have a 2.7 4 bolt sitting on my desk...

Looking at your location, I bet your injectors are already maxed.

Yea.
Scan it. I was running 143% duty cycle on the 42's with the OEM 3.06" pulley. That was on the GM tune as well. I dialed it in (got some help on it) and it was still 130% duty.

Ok thanks for the tip. I'll do a couple of runs on the VCM Scanner with the 77.9mm before installing. If not I'll just jump on some 80s
