Uhhh dude, I could make your car dyno 600RWHP if I wanted. It's just changing a few parameters around. Oh and BTW the alley isn't that bad lol. Seriously go read the thread, the guy even admitted that his car either has mods he doesn't know about or the dyno is messed up. Vipers are finicky cars on the dyno, things have to be set up differently. If you think those numbers are just a bit off, then I would like to have some of what you are smoking
A stock GTS dyno's about 415/450 give or take 10 HP each.
BTW just for a comparion on how fast the C6ZO6 is comparted to a Gen III Viper, the Z ran a 7:42 on the ring, and the Gen III ran a 8:10.
Have you ever ridden in a C6Z06? If all you have done to your GTS is a delete and catback and your SRT is stock, then yes, every C6Z06 you have come across has had a bad driver. Sorry man not trying to get you spun up, but it's just not going to happen like that with a game driver.
