Sounds to me like you need an AFCr or SMCand a missing linkwww.importparts.com.Get rid of the rising rate F.P.R.The missing link should get rid of your map senser code.Dont use those cheesy check valves.

It goes on the throttle boady where your mapsenser goes,then you bolt your map sensor on to that.becouse this spaces your map sensor off the throttle boady so it reads less pressure under boost .I put the link up for you on my last post .Click on it!

You could also go here for a missing link http://www.synapseengineering.com
That is probably your problem. I'm not sure about those injectors though. That's kinda big for not having any type of control to slow the pulse down. Keep the idle fuel pressure at 40 psi. That is all you should need.
Instead of using the missing link and the FMU I would seriously consider going with an S-AFC and some 450cc injectors. You will be much happier with that setup.

Re:eratic idle after bost
i agree with doc. maybe the 370cc injectors and the pump are flooding it at idle.
usually when some1 installs a pump it raises fuel pressure whether or not you changed the regulator. i bet your pushing 50psi w/ 370cc and flooding it then the ecu impliments its stall saver and pops the idle up high.

Re:eratic idle after bost
If you get 450cc injectors I dont even think your car will run without engine manegement.You need an S-afc or an SMC.This will control your injectors.DUDE you're putting too much fuel into your engine.You need to lean out your mixture with a fuel controller.Here is the link for the SMC.This will work to controll your fuel demand under boost.userwww.sfsu.edu/~ecg/index.htm
