I would definitely jet up with it in the car to start with imo.

We were going to, but pulled a plug n it looked good, so that's when we dropped timing n still made pretty much same power, but carried it out better without dropping near as bad. The EGT'S Were pretty much the same with more timing, so that told me it probably wasn't lean, plus the plugs were good.

Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
