Stock LS2 vs. Bolt On's
I have herd stock LS2's are making between 340-360 rwhp...Oldmansan's made 370 
Haven't dyno'ed mine yet, so I just thought I'd see what you guys are getting.
What are you guys getting out of these mods:
Spins ported Fast and TB
CAI (Halltech)
Headers (LG)
160 t-stat
Thanks

i have an LS2 A6 with the LG pros w/cats, Vararam w/spacer, Spin's FAST 92 with non ported tb, 160 t-stat and all that through a yank 3600 and 3.42 and pulled 371 RWHP and 379 RWTQ. i had my car dyno'd at mike norris' shop and he said it might be reading about 10 low so maybe it should be 381ish and 389ish.

Take the dyno numbers with a grain of salt. Some dynos read higher than others. You're best to use a dyno (the same dyno) as a gauge for your baseline and to determine what your mods are worth (over your baseline).

I have a Vararam, Spin ported intake & TB along with AR Headers and put down 381/382. I have not re-tuned the car yet after putting on the headers though.
Car runs great and plan to get the Spin cam + an UD pulley at the end of spring.

I ran the SLP on my 05 GTO with no issues.I was expecting to only hit 420-430 after it is all said and done, I always seem to have lower dyno numbers than most
The TF's are great, you will probably see 475 + with all the mods you are planning.
