I am new to the site and my friend told me that this was the place to post questions. Let me start out by first telling you about my car. I have a 2000 SS and have upgraded to the LS6 intake, also upgraded the fuel pump, ported the throttle body, and have Diamond dished pistons -8.6cc. I am looking into getting a heads and cam kit from Texas Speed. Heads are LS6 stage 2.5 port and the MS3 cam. The specs on the cam are 603/609 lift and 237/242 duration with 112 degree lobe sep. Heads have 2.02" Intake Valves, 1.57" Exhaust Valves and PRC Dual Valve Spring Kit with Titanium Retainers, Rated to .660" Lift. How much HP do you guys think I should be pushing before a tune?

 

Sorry I also have Long tube headers as well.
