Ford 4.6L 3V with a Paxton. The map signal is not steady at steady rpm. I'm curious if this is common.

Some fluctuation is normal but it really depends how much oscillation you're seeing. If the MAP signal is varying significantly it's going to be difficult to maintain a stable tune.

What do you do to calibrate for this situation Andre?
