I have an 02 ALH, has a VNT17, 1019 nozzles, stage two cam and I deleted the EGR.

Car will accelerate awesome and has good boost when I keep it full throttle, as soon as I let off the gas it hits limp mode and I have to reset with key. I have cleaned the map sensor and it kept it out of limp mode for 80 miles and then it kicked back into limp mode. Here are some screen shots of the car without the engine running. I don't know what the numbers from the VCDS mean, can someone help me out here. Im not smart enough to upload the pictures so ill tell you what they say.


Engine off key on

boost specified= 180
boost actual= 984


air mass specified 850
air mass actual 1275


mass air flow actual 1275
F96 BARO 840
MANIFOLD PRESSURE 984

FAULT CODE THAT POPS UP EVERY TIME RESET IS

16492 MANIFOLD BAROMETRIC PRESSURE SENSOR G71 F96
P108-35-10 SIGNAL TO HIGH-INTERMITTENT

I put on new vacuum pump, new lines, new n75 and tested the turbo actuator and it checked out good. Please help me know what I'm missing here. Thanks in advance
