just finishing up my t3/t4 setup- am i forgeting anything here...?

[quickersol]

the engine was compleatly stock before i started. i have added:

turbonetics style cast t3 mani
t3/t4 50 trim .63ar stage 3
tial 35mm wastegate with 5psi spring
dimond star motorsports oil lines
custom fmic setup (24x12x3.5 core)
turboxs Racing Bypass Valve Type H34
3" turbo back exhaust, no cat, megan muffler
dsm link
Sieman Deka 720cc injectors
autometer boost guage
autometer egt guage
walbro 255 pump
4 guage pump rewire (had it laying around so why not)
ngk plug wires
plugs
custom intake tube and filter
act 2600# clutch


am i missing anything here? will the 5psi spring in the wastegate hold enough boost or should i switch to a larger spring? what kind of boost levels should i be able to i run (i was hoping 22psi pump and 28psi race)? any small parts i should be considering?

thanks in advance for any help! the car is just about finished and ready for the dyno. should i break the clutch in prior to the dyno session?

An AFPR. 28 PSI might be pushing it with the stock internals. Also a set of cams such a 272 cams.
