found cause for losing manifold pressure

[Jerry De Santis]

Johnny, That does not mean they cured the problem. I'v done that to see if the turbo is putting out a good boost and eliminate the turbo as the problem. You should get full turbo pressure when the pressurivation is in dump mode. In my case, we found the exhaust tree feeding the turbo had large cracks.

Wow, I find it hard to believe that your cabin leaks are so big it effects the MP.

Anyone else out there have any thoughts on this?
