Don't try to rush out and do an errand while in the middle of a boost controller install! I had the stock boost controller totally out of the car and had to run out, so I just hooked the pressure hose from the turbo outlet to the wastegate to keep the boost down until I could come back and finish the job.
The ECU does *not* like it when you remove the boost controller. Anything resembling boost (less than 0psi even) will result in sudden fuel cut which will quickly and embarassingly stall the car at low rpm.

I'm guessing you disconnected the boost control solenoid's electrical connector, yeah, that does that.
When you finish the boost controller install, you'll need to leave the solenoid still connected to its electrical harness, or replace it with an appropriate resistor.

MAP sensor? no...I'm not that silly!
I'll just leave it plugged in, it's not worth the effort to make a replacement.
PS: the profec b spec II is really badass.

We also have pressure sensors that are used to measure both manifold and atmospheric pressure (the former more often than the latter). Fueling is primarily a function of the MAF sensor's signal and not the pressure sensor's signal, though.

Another thing:
If you leave the vacuum line for the diverter valve off, the car will be hard to start and will almost stall, then surge to 2000 rpm.
We need to start a thread with various known problems. That way, you could just check one place for any problems.

Well aint that some shit. I learn something every day.
Hey IronMonkey thats not a bad idea. The common problems with these 10+ year old cars with the most likely solutions would be a damn useful thread. I bet it'd get sticky status!
