Well that's interesting! Ross is a really neat guy. And its really easy to get in there to dyno if you catch them on a good day. You also can't beat the price haha.
I know what you mean, it really wouldn't be any problem to upload a new tune when going to the track. I may just go with the 4" exhaust and cutout eventually...we'll see.

I just went ahead and overlaid the two graphs....it is really remarkable how much power I gained going from closed exhaust (SLOWmaster) to 3" cutout.
The final damage is +70rwhp/+84rwtrq.
Check out this insane graph. It literally looks like I jumped from a built 346 to a 427 lol. It feels like a completely different animal cutout closed vs. cutout open. I'm also not done yet, there is still some more exhaust mods to do (dual exhaust or 4" mufflex), FAST LSXR LS7 ported intake.
