SR has been rebuilt. Was running well for the first 1000 miles.
But its like it happened over night or I just wasn't keeping track of things as well as i should have.
Car noticeably felt slow under load. Like slower than KA. Cruising feels fine but once i get into boost there is no power. Just noise.
The car runs noticeably rich at idle, so Im guessing things get ugly once under load.
Changed CTS,checked timing, have pulled my fuel rail multiple times checking for leaky/stuck injectors,tried a different FPR,checked for boost leaks, etc etc etc.
Changed oil and like a week later i had to change it again because of gas in the oil.

Also when I pull the spark plugs and look at the top of the pistons there seems to be pits (detonation Im guessing)
Can knock sensor do this?
MAF?
Compression test time?

This has been driving me mad for like a month now and i dont drive the car any more in fear of any internal damage from the gas in the oil. so an help will be greatly appreciated.
