Does anyone know off the top of their head what Matt has the shift points set at? Ever since I put my stg 5 Elite trans with G**rhead built trans tune in I get what seems like traction control trying to limit wheel slip. But here's the thing my truck doesn't have traction control. If I flat foot it from a stop at the top of first gear when the tires break loose the truck defuels then shifts to second loosing all boost and then it does the same from second to third. The only thing I can think of is I changed the max rpm in my engine tune to 4200 and maybe the shift point is at the same rpm.
