twin problem
i have been on top of my stock twins for a couple of days now and i just cant seem to find what the problem is,all the actuators seem to be good and all the vacumm line seem to be connected,when i drive the car it revs to like 5500rpm then it fall flat on its face the boost guage reads 15psi at the 5k rpm mark so its overboosting bad.i dont ever feel the secondary turbo kicking so whats going on?
i dont wanna go non sequential, i want to find this problem

well i bought the car with the primary turbo leaking oil and it was smoking like a bandit so the car was never runing 100%.i took the turbos out and replaced the primary turbo and fixed the smoking.now that i am able to drive the car with out smoking people to death now i found this new problem.i downloaded that twin turbo troubleshooting write up and checked all hoses and actuators.everything seems to be working but i still get that 5k rpm power drop and boost spike

If you still have the main catalytic converter in place, then it seems like you have a wastegate issue. I would troubleshoot the wastegate and pre-control solenoids:
http://www.autosportracetech.com/RX-...leshooting.htm
"If boost pressure is way above 10 psi, (i.e. spiking at >14 psi) then the tube between the Primary Turbo Compressor and the Turbo Pre-Control Actuator has popped off. Do NOT simply plug the popped off hose back on as it will pop off again. always use a new small hose clamp or a nylon zip-tie / ty-wrap for these hoses."
Start there...

When the car is parked and I rev it should the primary turbo waste gate actuator move?
I noticed today that when I would floor the pedal when parked the car would boost but the actuator wont move. I decided to check the actuator a second time with a vacuum pump and it moved when I applied about 10psi of pressure.
