98 bolt on dyno 98 m6 99k miles with the following mods:
ARH LT's w/ catted Y
TSP rumbler catback
FAST 90
Dynotuned by Ryne @ CMS on Dyno Dynamics
349.2 HP
363.97 TQ
Waiting to get the graph scanned to post it. The power fell off at 5500 rpms, probably due to tired valve springs. Tq was 320 at 2500 rpms and peaked around 4200-4500 rpms. More proof that a FAST 90 on a stock motor wont kill the bottom end.

Nice numbers! I've always wanted to see what a 90/90 set-up would do with just the bolt-ons you have. Your numbers were probably not too far off from mine before you added the 90/90. What TB are you using?
I was hoping to add a new Weiand Street Warrior intake along with a RevExtreme CNC ported TB but it doesn't look like it's going to happen since Holley/Weiand keeps pushing back their launch date...
Post up your graph when you can...I may end up doing this knowing I'm going to do heads/cam in the near future.
Thanks!

Me and you are in the same boat, I got the AFR's sittin in my garage, just waiting to pick the right cam and get some time to install them. Im using a bluemaxx TB, its a copy of the nick williams, and a nice piece. Ill post up the graphs when I get them.
