Good for about 10-15 I belive depending on the setup.... I gained 12hp with a fast 92 and ls2 TB non ported. You will take the full benefit since you have heads done, that's my next step.

I upgraded to a Fast 92 & CNC ported LS2 tb and noticed better throttle response and a bit more power from the butt dyno - have not run on the real dyno after yet.
In total it cost me about $1,000 for a used Fast 92 and LS2 TB so maybe not the best HP per $ but you are like me and running out of non-power adder options for more power.

It's worth 20+ if you buy one ported. There is a lot that can be done porting wise that will help over bolting a stock one on.
