To start out, the car was parked for about two months in storage, due to Indiana winter. I did start once a week throughout the storage.
My problem is when I get to about ten pounds of boost, I get a backfire or pop through the throttle body and the boost gauge jumps to about twenty pounds very quickly, before I can let off the throttle. Does it moving when rolling into it just enough to build boost. Have only did it twice in fear that I may cause damage to internals, jacking around with it. What I have done: Pulled both valve covers and checked to see if all rockers are moving, which they are. checked all hoses from breather up to turbo for holes and to make sure one had not slipped off. Not getting any strange reading on scanmaster!
Although today running with the hood open I was listening for vacum leaks and I could hear a grinding noise at the down pipe puck and if I move the lever underneath that controls the puck the noise goes away, the sound is almost like the puck is riding on the fins of my turbo, could it be related to the problem I am having with the backfire? It is a th 3" dp
Any suggestions would be great, stumped and need places to start looking, downpipe is coming apart tonight so i will keep you posted on what I find in there. Thanks in advance
