alright so i was gonna do a compression test on my s14 sr today but when i pulled the first spark plug i come to find it with a white tip... now im running 12lbs full 3" exhaust and a walbro 255 fuel pump and stock injectors... but i recently upgraded the fuel pump cause for a while i was running the stock fuel pump and at 12lbs of boost. Now could that have been the reason for them being white
