Since having the dashhawk I've noticed I get some knock 4-5 just about every morning in about the same spot. I think it is just after I accelerate up to speed (50 ish, not hard acceleration) after I get out of my neighborhood and onto a county road. The engine is usually warmed up to about 150-160 by this time. I think it happens as I cruise in 4th or 5th gear. Just pops up for a second, and then goes away.
Well I'm still getting it at tip in, sometimes up to 7.4 not sure what to do.
