R1outcast: If you stay at 10 psi, you are probably fine with the stock ecu. You will have enough fuel, but the timing may be too advanced if you are running a lot of mods. The other issue with running a lot of mods is actually maintaining 10 psi without spiking or creeping. If you can do that, there's no reason you need an ecu.
Scrub: Just set the target boost levels on the PFC to higher than you are boosting with the PFC to avoid fuel cut. That's it!
Houdini: As Insomniac (how ya doing Phong?) pointed out, mounting the solenoid on the fender wall behind the ABS is a good spot. It is relatively cool there and there is already a single unused hole for mounting the solenoid (I only have it attached with the one screw). I have had no issues at all with the solenoid being mounted there.

ummm dude that didn't make sence....but Im guessing you meant set the boost on the PFC higher then on the Profec

Gotcha...thanks guys. Now who has a link to the vacuum line diagram that shows where the boost controll solenoid goes?

*Remove line from turbos to wastegate. It should be about 4" long and will most likely contain a restrictor pill.
*Run a new line from the turbo to the "IN" nipple on the Profec solenoid.
*Run a new line from the "OUT" nipple on the Profec solenoid to the wastegate nipple.
*Unplug the line from the stock wastegate solenoid to the wastegate (at the wastegate). Plug both the now open nipple on the wastegate and the unconnected line.
Any questions?

Are you referring to how to install the Profec solenoid in the turbo control system? If so:

Great...that looks like fun.

Another tip: You should not use the plain vacuum tubing that Greddy provides to run from the solenoid to the control unit. The soft vacuum line may get pinched by the firewall penetration and that's not good. My mechanic recommended reinforcing the tubing with the hard plastic vacuum tubing that is used for running mechanical boost gauges.
