I think you are still missing a point here. Let's say I set my controller for traction from a dig (which is EXACTLY the way it's set). Let's say I have it set by RPMS. Let's say that from a dig, 8400 RPMS (1st gear) calls for 50% of my total jetting in order to maintain traction. Sounds good right? That setup ROCKS for digs and I never cook the tires. HOWEVER, when I am doing a 60 pull I drop to 3rd - 3rd gear at 8400 RPMs I COULD go 100% of my total jetting and still have traction - BUT the controller is locked in at a 8400RPM = 50% of my total jetting. In this senario I am only getting 50% of my total jetting when the gear (3rd) is high enough to not over-rotate the tires w/ 100% of the jetting. Now can u see how TPS or RPM can not be as good as a true "scramble" NOS program (which to my knowledge does not exist). I DO admit that there are LOTS of functions that I can use on my box - but for all intensive purposes you really have to choose between a "dig" progam or a "roll-on" program. The same program simply can NOT be used for both "to my knowledge".
