WHat setting are you using to make your best numbers or fastest times at track. Running tst twin program newer version wondering were to start. I am going to try and get it on the dyno in two weeks don't know how many times i will get to run. Would like to be in the ball park. Then be able to just fine tune after first or second run. I know all trucks are different but surely someone has close to the same set up that has been down this road already that can help get me close. Set of pants is hard to tell. Anything over 4-4 it will spin the tires when ever you ask it too.
