I have ATR WASTGATE on my 87 Gn with their
stainless steel headers 3 inch downpipe and 2-1/2 exhaust
from the cat back. Under boost I'm noticing boost creep
goes from 10lbs then when car shifts gears bumps up to 15lbs
I drove the car today again and now the minimum boost is
15lbs under wot . Should I be looking for a vacuum leak
in the lines leading to the wastegate or do I have a wastegate
problem..any feeback would be greatly appreciated
