    Default 98 305 swap to a l31 350

    I just swaped in a l31 350 into my truck that used to have a 305. Dealer wont flash me a stock l31 tune becuase i dont have the matchin vin for the 350. Does anyone have a 98 stock l31 tune i can load into it. Or is this even possible?. I have a v2 with efi live.

    Thanks Jeff
