I just dynoed my car and its running a nis tune with the following:
Z32 MAF
S15 T28 BB turbo
deaschwerks 550cc Injectors
Nismo Fuel pump regulator

Its only doing underneath 200hp Im guessing its the cam timing but if it isn't what else do you guys think it could be?

Wow, yeah that's horrible. The local(ish) NIStune tuner near me usually gets 280-290whp with similiar setups to yours (along with full exhaust, FMIC, etc.) You've got something seriously wrong going on. Is the motor healthy (good leak down, compression, etc.)?

check your compression.. somethings not right.. possibly the nistune is your problem? or a shitty tune?
my old s13 sr with a blitz tuned ecu and bolt ons did 268 at 13.5 lbs. stock injectors

everything is healthy on my car just blew out my s15 t28 BB tubro couple weeks ago and bought a new one and injectors and its running like shit so it has to be timing right?

Wow....!:tweak:
How much boost?
I wanna see your logs, you did log your runs right?
I would be pissed at my tuner for that shit unless it was 7psi and why would you dyno the car if it's running like shit? You probably have missed understood the dyno tuning concept. post some video of it running like shit.

Start by syncing your timing with nistune or it will always be off with any consult program.
If you put the chain on following the instruction then it's correct, that's mechanical timing. Move onto base ign timing, This is the cas position read with a timing light on the crank pulley. Mech and base correct!

piss poor way to spend $1400 est, that's almost a new engine.

No Logs?

The intake cam was retarded by one tooth, that is why it would not make power. It is tuned now and runs good.

Here is comparison of the final pull tuned with the "best pull" with the intake cam one tooth retarded.
