i already have the FAST 90/LS2 90 on my car and tuned. About to take my car in next week to have the clutch replaced. While it was in the shop, i was going to have 4 more mods done. I'm currently running the MS3 with TSP ported LS6 stage 1 heads. how much more power would i pick up with a ported tb, ported FAST mani, ASP 25% U/D pulley, and Meziere electric water pump????

 

That depends on other things, but should be around 20 or more.
