I guess I've picked up some power from my new tune...just blew the rear end from a 40 roll, no brake boost etc. Anyway, I won't be able to verify 100 percent what's wrong until tomorrow, but there is no external damage/holes etc. Assuming that it's the ring/pinion or diff, what's the best fix/upgrade?

 

id give TRE a call

 

790 is a lot of power
