wot 4 gear
You can wreck the trans and/or the engine. 4th gear in an A4 (5th/6th in M6) just arent designed to handle that kind of abuse. I know its not an LS1, but Ive heard of quite a few people losing the motors in the Lightnings due to a WOT 4th gear pull.
I see you have a performabuilt tranny, but i would still refrain from a wot 3-4 shift if at all possible.
