interested in seeing those with 5.3's 220/220 plus cam and heads
With added compression having a time figuring out timing and completely getting rid of kr.
When I stall up in 4wd I get some knock, the knock always seems to happen around 1800 to 2400 rpm with medium load. Sometimes its there sometimes its not. I wouldnt worry about it if I wasnt running a 20% mix of 110 and 93, so I think its real knock. Its just spuradic I cant figure it out.
At wot nothing. with cruise on highway nothing. around town I get it?

Also how long does it take for the fuel trim levels to adjust themselves?
