[mdbm1026]

i just bought this tuner(u7194) (v.9r10) and i have no clue all it has is an 87 tune and diablo tune ... and i ran diablo tune and cant notice a difference in it the truck doesnt shift hard at all and can someone give me specific parameter adjustments on it so i can set it... i would really appreciate it... i am tired of getting beat by fords .... but i am scared of adjusting parameters because i havent seen a tuner that is this in depth and am not used to it all i have is a flow master 44 series exhaust if that helps... thanks if you can help you are a life saver

because ur on the economy tune u need to go to the 93 tune and go to premium gas ya it sucks but we r power hungry people

There is no 93 octane tune for trucks. The Diablo tune is for 91 octane fuel. Install the tune, drive for 50 plus miles to let the ECM relearn the new program. The truck won't shift any different since there is no tranny adjustments available on the NBS trucks.

yep, install it run it for 50 miles or so, download the tune and get you a custom tune on it.
