you need to read the file out, change the tire size, and reflash.

If your using any of the tuners currently on the market, you will have problems to my knowledge.

May be worth investing in HPtuners or LS1Edit to read out the file. Or if you know someone who has it, perhaps they could do the tire modification for you.
