No power from turbo, could it be MAP sensor?
First off, this forum is awesome. I've spent about 20 hours searching and reading threads and I'm starting to get a hold of what this engine is all about. I'm no mechanic, but I've done my fair share of work on all my vehicles. Here is what I have going on:
2003 pure stock.
Symptoms: no power from turbo, shifts fine, runs fine downhill, but going up hill barely crawls.
I've already checked and/or eliminated as possible causes: Turbo (it's a new turbo, can't hear any leaks out of any hoses, CAC, cic.
On the scan gauge I'm getting fine FICM voltage, good icp, good vgt.
HOWEVER, the scan gauge shows -1.3 boost at all times, and 11.3 MAP at all times. I'm thinking this could all be the MAP sensor.
Would a bad map sensor cause the no power from turbo issue?
Would a bad sensor cause there to be a constant reading of 11.3 on the scan gauge?
I've spent a lot of time and cold nights on this thing, but I think I'm getting close. Thanks in advance.
