we had a 2000 corvette that came in for a tune. we unlocked their computer began to tune found a few issues with the stock computer found out it was bad. we replaced the computer with a new ac delco ecu and reprogrammed it thru the gm tis site with the correct vin. the problem is we no longer access the new computer with hp tuners even with the ecu having the correct vin. is there a way we can access the new computer without having to purchase new credits again?
