reading the trans is great too as long as the tuner knows what they are doing.. getting the 4-5 upshift time waay down helps em live also. I just dropped a good bit of coin and love the truck, so I want to not have to **** with it all the time or be fixing stupid **** all the time. but know full well whats to be easily gained by putting it on a diet. and know what e.g.r does to an engine. (deal with heavy diesels for a living)
and like most of us I have this problem with leaving **** alone. its a sickness I think . haha
