EmergencyVP1 Posted May 12, 2006 Report Share Posted May 12, 2006 So my Nelson tune comes in today for the SS. I had one on my '04 2500HD crew cab and it made a hell of a difference on that. A few times I could smoke the 285's on it I spoke with Nelson and decided to go with the 91 octane tune. He said the next thing I need to do, is get the servo and a shift kit, then we can wipe torque management out of the tune and lessen the shift firmness, since the kit will take care of that. Will let you all know how it goes. Should take about 4 or 5 days for the computer to really respond nicely. Quote Link to comment Share on other sites More sharing options...
