Which Programmer will let me turn on the high idel, adjust tire size, horse power, ect...?

Booger

BullyDog will let you turn on high idle but I don't think it will work on the 6spd. Edge/Attitude will adjust for tire size. I have used both and both make great power. The Edge is not a programmer, it mounts under the hood.

Speed Shift

The Smarty will do what you want, but you are going to need a clutch, and a fuel system if you plan on useing more than #3. The 6 speed can be fixed for high idel with a wire to the ECM. I have it done on mine.

I noticed you are from Poteet, I am from Somerset, you have probly seen some of my toys around....

The Bullydog with the outlook will adjust for your tires but the Tripledog alone won't adjust tires but it will do the ideling adjustment.
