My idle is still 800 rpm, and once in awhile if its really cold/and or idling after a hard drive, the car can tend to stall, but I don't think that has to do with fuel system as much as the stock ecu just reading wrong with the larger injectors and having to pull the air through all the piping.

Anyway, I would say you shouldn't have to worry about it until you want the bigger hp numbers. Just follow Phunks advice. We are working up to 450 whp and so far have had no issues with lack of fuel.
