I am having my 06 GT supercharged with a custom dyno tune. In addition, I ordered new wheels/tires that have a different overall tire diameter than stock and are 50mm wider than stock rear tires. I was told that I could have the s/c installed and tuned with the stock tires/wheels and that the later addition of different sized tires/wheels was irrelevant to the dyno tune. Is this true or false?

Dyno tune has nothing to do with the tire size, it is about tunning the air fuel ration with the spark and timing when the engine is under load and reving up thruout the whole rpm range. It has nothing to do with the tire.
