any issues so far with this setup? I'm going to send my chip in for a reburn on monday, and have it come back with a 6# lower setup. I think I may ditch the 4.10's as well, and do the stock 3.55's. Anything to look out for? The car isn't driven much(on the street) but I'm concerned a little about the heat this things i going to make....it sees some track time that's for sure, I gotta learn to get it out of the hole!
