Hi everyone ;o)

I know the PFC can control boost to a certain degree, my question is that my car has a Greddy profec b specII boostcontroller to cotrol the boost, but when I go into the Commander I can see the boostcontrol is ON, is that right when I have the Greddy to control the boost ? allso, the motor has just been rebuild and the wastegate has been ported to prevent boostcreep, but suddenly my primary turbo will not start spooling up before I hit 3000 RPM ! has it something to do with the porting ? and if, what can/should I change in the PFC or boostcontroller to spool up as before ? or could it be something else I sholud look for that the turbo has this behavior ? I have the stock twin turbo seq. and before the rebuild/porting it worked just perfectly, hope some of you gyus can help me with this as I do not have big knowledge about the twin turbo system, thank's a lot.

Best bet would be completely disconnecting Profec B and trying out default connection/settings for boost controll in PFC.

 

First u have to check the Turboconrol on the Turbomanifold. To check this, start the car revs a couple times an shud down,then turn the key on-of-on-of 3 times and look under the care to check the Turbocontrolactuator works and under the Hood that the Turboprecontrol works. If not chek the Solenoids(elektrikal ok) and the Plastiktanks of leaking.

 

Thank's a lot guys ;o) I will into what you suggest, and let you know when/if I find the problem.
