Stoped doing them at the dealership cause so many broken tranny's

My AWD SS trailBlazer ran a 14.2 stock.. With just a Tune and a CAI it went to a 13.5.. I put a 100 shot and went to a 12.3@109 The TBSS weighs 5200.. The Tune is just unbelievable for GM products... And I just got a Vector Race TCM that is suppose to be good for another 2 Tenths.. Plug and play... Also When I was at the track there was a CAI and Tune only SS Silverado with the same Tune as me running 13.8's @ 100 MPH Put A 4000 Stall in it And Run 12's.. Im willing to bet there is not many stock one's out there..
