[R34 rocket bunny sedan]

OK so need some help please people just turbod my na r34 and am checking if what it's doing is OK before my tune on Thursday OK so I'll start with parts I'm running... And post problem last

Rb25de neo 

R33 5speed gearbox conversion 

Was using rb25 one but think was near dead New rb25turbo hasn't arrived yet 

R33 turbo manifold

Gtt injectors 

R32gtst4det fuel pump

Power FC ecu stock gtt base tune atm

Big front mount cooler

Turbo smart bleed valve 

New 3"pipe decat and r32 custom dump

R34na 02sensor

R32gtst4det afm I wired in also tried 34 na one OK so my problem is it misses bad under boost only.. disconnect turbo runs sweet can this be my ign timing when boosting?  Just want it all good and ready for my first tune as never had one what should I get done in the tune and what boost 5? And just get fuel/air and some timing pulled/retard etc...also haven't tried yet as my new turbo is on its way but the one I was using was blowing smoke and whining and no matter what it was stuck on 7-8 psi my hand controller wouldn't turn it down so waste gate? Over boost could've been the problem?

Let the tuner tune it. Don't have to tell them what to do.

Don't boost it until it's tuned or it won't last long.
