boost problems
everytime i get to 5 psi on the primary turbo at any rpm, the engine cuts out, and the engine starts to cut out and sometimes back fire a few times.

Hey i have had a few boost probs my self, as soon as boost came on it would start breaking up, the first prob was that the boost gauge was off and it was boosting more than i thought and was cutting out on fuel cut, so mayb check your boost gauge, set one up temp and check boost again, and the other time i had this prob it pretty much did exactly the same thing and it turned out to be blocked injectors, i ran put in a double dose of cleaner on half a tank of gas and drove in second gear at bout 80km/h for a good 15-20mins (the reason for this is that it works the secondary injectors )and then drove normal, i gave it a boost and it coughed and splutterd and blew out a hugh cloud of smoke and i have never had any probs since with the boost, this may help, thanks mark

i reset the ecu, and the car still cut out at 5psi, but i kept driving it, and it slowly came out of it, possibly clogged fuel injecters or fuel filter? although now i have sequential turbo issues, it came out of cutting out, but now the secondary wont kick in, i checked my vac lines to both cross over valves, and they seem to be fine. also, what is the spool time for the primary, mine hits off idle, to about 4 then goes naturally aspirated. this seems to fast of a spool time to me, it is a small turbo but seems like the cars egts would be to hot from that. i dunno me confused. maybe u guys can help me.......

no i didnt check for boost leaks, all hoses and charge pipes are in good shape and are in place where they should be. doesnt mean that their isnt a leak but, i cant see one if their is. im runing good vac and running 7 on the primary side. everything is going good now until the secondary is suppose to hit. this motor is fresh so im trying not to bring the rpms up or run it too hard of course. that seven on the primary is hard not to hit because it runs 24/7 off idle until 4. i havent given the car half throttle yet, this is all based on creeping the rpms.

"The Turbo Control Solenoid / Actuator is one of the more complicated actuators as it requires both vacuum and pressure to operate properly. This actuator is controlled by two solenoids, (both are wired together to the one ECU output) one solenoid applies pressure to one side of the actuator and the other applies vacuum to the other side of the actuator. With pressure on one side and a vacuum on the other side of the actuator, the speed of the actuator is improved. A typical problem is loss of Secondary boost in 1st or 2nd gear at 4,500 RPM, but reliable operation in other gears. This points to one side of the Turbo Control Actuator not getting it's pressure/vacuum, so it will still operate but not quickly enough."

currently i ripped the upper manifold off, and i found the secondary fuel rail lost its vacuum line. would this enable the secondary turbo from spooling. well its a good thing it didnt spool but i was wondering if thats my problem
