Guys could you help enlighten me what could be causing a high KPA reading at almost all TPS points and loads?
I am seeing nearly 90 KPA at 22% TPS... 50kpa at 0% TPS??
The car read the exact same with a brand new MAP sensor.
The car in question is a 24X Converted LT1 with LT4 Heads/Intake, and an unkown Cam. Running a modified 2002 F-Body profile in the PCM
Any input would be appreciated!
I've seen low rpm idles at 80 90kpa on heavily boosted cars but NA should be 30ish. Log and tune please

Vacuum leak or valve adjustment issue.
Well the valves are set pretty loose, right at zero lash with no additional turn.
I will do a vacuum check, I believe we did once before and it was a very low vacuum. Maybe 4 or 5 inches
The tune I was running around on was set for MAF tuning. But it does it on any tune.

Heres the log...
Doesn't look bad , just the wideband is set up funky , I posted a solution in your other thread.
