What BOV do you have? Does it have an SC spring in it?

[overclocked23]

i just have a drift bov guess just a turbo bov did not think ther would have been to much difference the bov is wound out want to let as much air out as i can when the t/body is shut

Has it been tuned properly? Not leaning out?

[overclocked23]

not leaning out once you put your foot down it goes fine , but when its cold and you put you foot flat has like a poping sound around the throttle body dont know if its a back fire

Was it dyno tuned or like a mail order tune?

[overclocked23]

it was a mail order tune

To me it sounds like some sort of fuel issue, whether its just in the tune or not i cant say. I am no mechanic. Hopefully its not leaning out otherwise could cause damage to your motor

I had all sorts of issues with my blown 5ltr, i think im on tune number 10 or 11 now and its still not perfect
