Hey guys do any of you know a sure fire phone number or e mail address to contact diablo sport because i have been trying to e mail them all week and call them on the phone, and i get no e mails back and when i call i get put on hold for an hour. I have talked to a couple guys on this site and apparently on some of their tuners you cant adjust the speedometer for gear changes with the "factory HP" tune and diablo sport offers a free custom tune for those with this problem. This would be nice, if i could only contact them.
