knock and timming im fighting an issue with my car falling on its face only at the top of first.
Today i hooked it up to a snapon scan tool and checked out the timing and the the knock
in all gears at WOT the knock reads 4 degrees and pulls the timing down to 23
i was told the car was tunned to 26 then had 2 degrees taken out for nitrous.
So i unpluged the knock snensor and the timing stayed at like 35 or so and the car still fell on its face at the top of first.
AF is at 13/1 or so and fuel pressure is at 60psi
should the car be reading 4* of knock like that?
