87tII boost qs

My car doesn't kick as hard when the turbo spools.
I have the following installed:
s5 knightsports hybrid to4b I think, thats what i was told.
greddy fmic
greddy 720s secondary
greddy bov
cleaned primary 550s
rtek 1.7
rb 2.5 dp
rb 2.5 pre-silencer
custom rb 2.5 dual exhaust
255 walboro
3" tid - 2.75 turbo inlet
air pump removed
acv removes
split air removed
twin scroll removed
stock port
I don't feel a kick when the turbo kicks in, are there any problems i may be having with my setup. i should be in the range of at least 250-260hp right?

Tune. Have you gotten the Rtek optimized?

What do you mean optimize? Its a 1.7 so i can't do any tuning on it.

Well, first I'd verify what turbo you actually have.

Second I'd verify that there are no vac (and therefore boost) leaks

Third, I'd go to a dyno

Well, on the compressor housing says knightsports on it. a few people who saw the turbo says i can push 300 on it easily.
i dont believe theres any vac leak because my boost gauge reads 20inch vac.
not ready for dyno yet beacause I'm getting it ready for paint.
