What I did... I loaded the diablo ecu/tcm first. Then loaded my custom tune but skipped the trans so just loaded the ecu. Seemed to of worked.. diablo trans tune and a non diablo ecu tune. Do you see any issues doing this?

I have a few custom ecu tunes and 1 custom tcm tune loaded on my P2. Would I be able to start with a Diablo Sport tune so I can make changes to the trans. Then install one of my custom ecu tunes after?

thx for the reply. what about the diablo trans tune? The standard diablo tune changes shift points and shift TQ correct? doesn't the tow/haul also do this with the factory settings? so does the tow/haul alter the diablo shift points and other options?

2010 Silverado 1500 w/6 speed. How does tow/haul mode effect a Diablo ecu/tcm tune? Does the Diablo tune also change parameters in tow/haul?
