I've posted logs of before I turned the boost down (02) and after I set the boost to spring pressure only( 04)
Story is - I was doing a pull on my way home. Temps were in the 40's for the first time and my I saw the boost spike from 27psi to 30psi. I was logging(would have to go back to find it and then post it for you alln if you need it) there was no knock what so ever so I stayed in it.
However the next pull i went to do. Any time I got over 15psi the just splitters like a blown I/c pipe.
I did a boost leak test (none)
compression test (160+ across the boards)
Gapped spark plugs .28
I checked wireharness plugs for the injectors, map, tps , gmait, and isc.
hoses to bov, wastegate, turbo, map
I also found the line to my oil catch can was loose son I tightened that down
Not sure what else to check. I turned the boost all the way down and other then initial hickup at spool it pulls fine by the buttometer
