as far as the launch goes... i get a crappy burn out...stage and leave at about 5000.. little to no slipping, just kinda easing the dumping...tiny bit of wheelspin, and a little going into second.... after that it just hooks....
I do have a NA diff sitting here...just pondering if its worth it..see next WED is the last Wed night of the season here, and My shop and I would really love to get into the 11's...got about 900 bucks to blow buy then.....
