I know the bins would be way different. Lol
Credits would be bought for the Bonneville. So flashing his. Gtp tune won't work, because of the vin discrepancy.
But will the vin be attached to the now saved ,in laptop , tune?
I can only imagine that a person who sells tunes , already loaded in an ecm, has to rewrite a tune for identical setups in say a Buick GS, and a Olds LSS , minus of course the vin change?
