We are tuning a customers Custom Weld boat with a Supercharged 6.0. Boat came to us not running well. I installed a PCM from a 2002 Express van and upgraded to a 2 bar OS. I am having two issues currently...
1. MAP sensor is only reading up to 105kpa under full boost of 7psi.
2. Cylinder air mass is only reading up to 32 g/cyl.
I have searched and obviously I am not using the correct search key words to receive the information I need. I have a feeling these issues are related?
Thanks,
Rory
