I guess I cannot adjust the speed and other config until I choose one of the canned program, right?
I'm still running stock, waiting for my customs.

Yeah, pretty much. When you do decide to try a canned tune, try 2661 as your tire size and use the method I mentioned earlier (using the odometer) to get it even closer. Also, dont forget "load previous settings" no matter what your doing, and check the gear value to make sure that is right. You might also be able to get the dealership to recalibrate the speedometer but I dont know if it would be worth the price or trouble. I know a friend of mine got his truck recalibrated at the dealership(because he wanted to get out of a ticket, if the truck really was off then they would waive the fee).
