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!
