Iv been around a few big boosted applications and had the problem with blowing spark out under boost. Obviously I'm not boosted but it acted exactly like that. I can't wrap my mind around why the gap made that difference but it did. I know a guy iv been talking too and he had the same issue in a n/a ls7 swap 5th gen also
