I may be getting some 20" rims in the near future (I'm still debating on whether or not to stay with 18's). Anyway, if I do get them is there any other way to flash the computer to recognize a taller tire/wheel size. If I go with 20's I may go with a 275/45/20 or a 255/50/20 tire, which are both taller than stock. I guess what I'm trying to do is not buy a programmer if I don't have to.
Will the dealership reflash for this? Or would it be easier to get a Predator tuner? And with the Predator can you just adjust the tire height without messing with any of the other programming options?
