It had starting problems and would run the RPM's all over the place until it warmed up, but no turbo problems, the turbo issue started after we pulled the dash, pulled the stock alarm and put in a new MAF sensor. This is when we saw the voltage start dropping. Tomorrow we are going to pull the dash and hit all the connections, if that does not work then we'll run the checks V6 recommends. What happens when the waste gate does not operate properly? Can a waste gate solenoid go bad? I do have a note from Eric at Turbo Tweak on some readings on the BLM of 142, I sent him and based on that he said I was running lean and MAF might be the issue, that is why we changed it.
Would be interested in hearing about the waste gate issue.
Thanks
