Once your tune is perfect then you can always have him email a copy. That way its stored in your hard drive. I have like 7 tunes at home... all from Doug and 1 from Cr at Tillman speed. As long as you have them stored on your pc you should be fine. Man I wish I could have Doug do a custom tune for me. I'm in NY so that's pretty much out of the question. Good Luck with the tune
I've personally had my Bamachip's custom mail order tunes, dyno tested by 3 different tuners..2 were on Mustang dynos, and the third was on a Dynojet..Each of the 3 tuners that did the testing ! told me that I'd be wasting both my time and money, as they couldn't guarantee they could squeeze any more power over my Bamachip's 93 race tune, even with any of their custom tunes on the dyno..That's how good they claimed Doug's tunes are ! You can either purchase a handheld programmer from Doug, that already has 3 of his tunes included ? or you can purchase the tunes from him separately (via e-mail) and then download them into you're existing programmer yourself.
