Okay.....I'm gonna try and make this as simple as possible for myself because now I am slightly second guessing what I should be doing!

Bill: My custom tunes were built without me specifying any change from the stock TS/GR!
My truck has 3:73's and stock 275/65 18's.........do you recommend I touch the TS/GR settings or not?
Currently I have my snow tires on and they are 265/70 18's.......again, should I just leave the settings alone?

I have tried playing around with many custom settings but I always keep coming back to your custom tune because it feels like it works the absolute best in every area........the only thing I tweek is the standard driving 1-2 shift and 2-1 shift. I drop it 1 because I want it to be slightly less aggressive when gently taking off from a dead stop!
