Stock wheels and tires after reflash?

[BLKTXDenali]

So I'm getting my Denali reflashed for my 295/30r26 and I was wondering when the time comes what would happen if I just put back my factorys without another flash?

well after alot of bs they told me they couldnt do it??? the guy didnt seem to know what he was talking about he said something like they needed a new v something number and they didnt have it for my size which hard to believe and they referred me to aftermarket shops for a power programer that would allow me to dial it in..........it was gonna cost 110 for re-flash and another 140 for the number bs thing and install. total like 250 plus tax wonder is anyone else has had a successful re-flash done like i was trying to do.
