Just wondering how much vacuum you guys see with Ford GT cams. I'm running 9.1:1 compression and a whipple 2.3 and I'm seeing about 16in of vacuum at idle, around 17in during deceleration. I just want to make sure this is where it should be. I'm having some issues with the car running rich at low engine loads and under vacuum and want to rule out anything mechanical related before I talk to my tuner again. I did a compression test today and it was between 185 and 192 across the board hot. gotta love working out the bugs on a new engine!
