Well, I've decided that The V will be getting a supercharged LS7 transplant in about a year or two. Since this will be sometime down the road, I wanted to get a tune for the stock LS6 currently in the car. I've tried contacting wait4me to inquire about their products, but to no avail. Other than them, would any of you have any recommendations as to which companies offer a good product for a few extra ponies? The car currently has a SuperChips hand held tune, but I don't want to get into EFI Live complexity as of yet. I'd absolutely LOVE to get rid the annoying burble and pop. Thanks in advance.
