Hey there guys just a quick question
I have an old truck with a boosted 4.8.
I am constantly seeing map sensor going all the way to 235kpa
Just wondering that would put me at 19psi right??
I have a 10lb spring on this thing and for some reason can?t get to to stay around that range.
Tried everything
Already drilled and tapped the turbo and installed hard lines.
Wastegate stuck??
