All of Doug's tunes are 75$ emailed. I don't know if he is running any specials or anything right now, but usually it's cheaper in the long run to buy his three pack for 180$
Yeah I think Bama is the only one the emails Diablo tunes. Why don't you take it to a shop and get it dyno tuned? Ask them to either give you the tune file(you won't be able to change it at all, but at least you will have it to bring back to them when you need it changed) or ask them to archive it. My old shop let me archive mine, but then again there isn't much demand for '95 metro tuning either!
