well guys all of a sudden my CEL is goin nuts around 3400rpm to 4000rpm on light throttle, anywhere for -14 to -9 reading on the boost gauge im getting knock. Anyone have an idea? it was hot as hell and humid yesterday. Oh and another quickie, me and my tuner couldnt figure this out, on throttle tip in, the engine instantly yanks timing to i beleive -20 degree's? this causes for a weird hiccup when i push on the gas lightly, we tried tuning it out but it wont, we shut off the knock sensor, nothing, put it in closed loop, nothing, any idea's?
