What power will I be putting down?

[CuRt007]

Hey guys,
Just wondering what power I'd be throwing down at the wheels with these mods.
Its a VT V6 5speed 3.8L ecotec.
Its got a Mace CAI, Mace 1.98:1 roller rockers and 2.5" cat back.
Also, if i got a tune, what extra power would i be looking at?
Cheers,
Curtis

I'm guessing an extra 15kw

If you get a dyno tune they will tell you how much power you are making.
