Thanks - yes, I've considered using an add-on or MS unit, but first wanted to see if a simple system would work since I'm not asking for too much power..... don't yet know if it will.

I'm using the 240cc injectors to hopefully keep the idle quality ok with the OE ECU.... but they do require a fuel pressure boost at full intended boost. If I went to a controller or MS, I wouldn't need the FMU, but would need to increase injector size. Before I went to another controller, I'd try 270cc injectors and peg the fuel pressure to ~38psi and use a 1:1 only regulator.... see if it would idle ok - if it would, there'd probably be no need for another controller, depending on how much the MAF influences mixture under the extra air flow of boost..... I still have lots of tinkering to do - but first I need to stop the leaks.
