That was at silver dollar. I took it to commerce one time, and it was about a tenth slower. Same senario though, drove it there and didn't cool it off. What programmer do you have? An old cobra I had, had the same mods as yours except for the exhaust. It had the factory h-pipe, and a mac cat back. With a diablo predator, it made 480 to the wheels with a pretty much perfect tune right out of the programmer. I didn't even have to make any adjustments.

holy hell. I have the predator with the box pulley tune. Im looking to get a borla stinger catback and ditch this factory piping. I've been hearing that you can actually make more power with a catted mid pipe vs. an o/r unit. You know anything about that?

Generally with an O/R midpipe you will loose slightly more low end, but make up for it and then some up top compared to a catted mid pipe.
