Yes, I’m certain. On my to do list is a 4 Bar map sensor. That total number includes the corrected atmospheric value for 9400 feet so 33 psi was still the absolute pressure in the plenum. The motor is capable of WAY more with a bigger turbo, the transmission is not.

Have pulled the pre catalytic converter and catalytic converter. They do not appear to be too clogged, but we are cleaning them anyway. Problem now appears to be intercooler or cracked piping leading to intercooler.
