I recently put down 443whp and 408tq with a TV2 cam, stock ls6 intake and AI 226cc heads. To finalize the build I had Vengeance Racing port my FAST92 to squeeze every last bit out of my combo.
The port work by Vengeance looks amazing... No complaints about their work whatsoever... Im just very disapointed that I only picked up 10whp with the swap... What does everyone think?
My friend with the a similar build only picked up 9whp from an unported FAST92 swap and a TV2 cam...
New parts for latest tune:
VR Ported FAST92
NW 92mm TB
FTP 98mm lid
85mm MAF
Mods before:
Torquer v2 cam
Stock ls6 intake
TSP 1 3/4 LT headers
TSP ORY
Powerbond UDP
Ported stock TB
AI 226cc heads
**443whp and 408tq

I would say the increase under the curve is nice even if you didn't see a big peak increase. Exhaust the next bottle neck?
I saw pretty similar results on my ctsv. With the v3 I picked up around 10hp going to a ported 92mm fast.
Also on a superflow so you may have picked up 15+ on a dynojet.
