Anyone hazard a guess at what output you could expect from the following mods on a V LS6.
LT Kooks with free flow cats
Corsa
CAI LPE or something like it
TPIS ported TB stock size
Stealth V Tune
Also would the 90mm TB with a modified LS6 intake or a FAST 90 be worth it with just stock LS6 heads and cam? What would you pickup in power for $900? |

I'll be able to tell you in a week or so when I get my "before" done. 
With or without the CAI, it probably won't make a difference.
My guess now? 350-360-ish.

You are in Wisconsin?
If so, I'd see Big 3 and let Tony fix it up for you, including a dyno run.   |

Yeah...I'd say between 370-380 rwhp and 360ish torque. Let us know how it comes out. |

TB? Like the CAI, don't think it'll give much if any improvement. |

Add a cam and that # changes a lot.$900 becomes $1200 and that 30hp gain may double. |

As soon as my backup PCM with Stealth Tune comes in I plan on getting dyno'd.
Mods are in my sig, so I'll let you know how it comes out. Basically the same as your plans, minus the TB.
