Has anyone ever experienced this before? I was at track last night, first pass in car, stage it on transbrake , leave hard, shifts 2nd and car hit rev limiter ASAP , car falls on face , hear it loud bang back in gear stab it and then boost comes on hard and feels like it slips again. Could it be in the tune or mechanical issue. Trans never got hot, still shifts fine out on street, just seems like under wot hard acceleration hits neutral when shift to 2nd. Any help would be appreciated.
