well i finally took the hoe to the track. got some vids and tune logs. it ran 15.95 best. but in my logs i find it gets real bad KR right after the 1-2 shift. what could cause this? i mean its running 16* of timming after the shift. i'm loading the vids on streetfire right now.

See, that restrictive magnaflow is holding it back. You should have bought a flowmaster, you would have run at least .5 better. lol

 

is your exhaust hitting anything? might just be false knock.. try bumping up the octane to rule out actual knock.. worse case, tune it out...

 

we i put 93 in it and it didn't really go away but i installed a turbo the same day so its hard to tell lol. i lowered the timing a bit at 4500 and the last time i got on it it wasn't there. but if it is the next time i'm gonna fix the tune for the sensors in that spot. i think maybe its just peak torque causing it or something.
