Vac Hose Diagram Need checked
I currently have the simplified Non Sequential vac hose diagram setup with the poor man's mod for non sequential. I want to get rid of the rest of the solenoids, and the following diagram is what I'm planning on doing. does anyone know if I'm deleting a needed vac hose that should not be? Thanks

Thanks, I probably would have caught that when i started pulling and pluging all the solenoids. 
anything else? I appreciate the response that way I deffinitely remember that one.

Difficulty with warm starts. That's it.
It's called the PRC solenoid for Pressure Regulator Control. I removed mine. I use only 2 solenoids - wastegate and evap purge.

Check the archives for Rikki's Diagram, its the cheapest way to do it. I may do it in a bit, lots of people have done it with and are happy. Lag is dependent on your exhaust. FULL boost at around 3500 to 4000 RPM depending on your exhaust. Port and full exhaust would bring this down to 3000 probably.

If you *bypass* the FPR solenoid (It's solenoid (A) in the diagram, orange plug, closest to firewall), then nothing will happen. You may find that it will improve your warm starts, because you won't be running nearly as rich.
If you leave your FPR vacuum line disconnected, then you will run very rich during idle and lean during boost.
