20v blacktop swap bogging

Sort of what I have experienced as well.
How long has it been since you`ve fiddled with ignition timing? If recent enough (within the last 500km) the ECU may need to learn a little bit yet. Don`t be afraid to drive the car, if your base timing has been set with engine idling in CEL mode, just drive around in normal mode (dont WOT it all the time) for around 2-4 weeks.

One thing is revving in idle, if you don`t drive the car under various loads there is no way the ECU is going to learn to compensate

I`m not too sure about MAP sensor, mine is connected to the vacuum rail on the intake.

Adjustable FPR is not a bad idea, you can fiddle with fuel pressure (2.3-2.6 bar) until you find the perfect sweet spot there as well.
