I run the dual plane RPM Air Gap on my 1200PA with a single Turbo. My motor is no where near as powerful as yours N/A but I think the dual plane works fine with the Fitech and I find mine has very streetable manners. I will be switching to a single plane Victor 340 that I have on the shelf, but that's just to see if it improves at the track (1/8 mile). Not sure if it will hurt street manners or not.
On your shopping list, make sure you run plenty of feed and return line. I have 1/2" (8an) feed and return on mine. They both terminate on an Aeromotive regulator. Good luck with the project.
