Bigger injectors on there own will not give an increase in power whilst running a standard ecu. Infact it will probably even lose you power and will certainly hurt economy.

Also a lightened flywheel will not give you an extra 30bhp. It will reduce the power lost through transmission//drivetrain but I would be surprised if it was the equivalent of 30bhp

With a power fc and the mods you have I think you could get 320 ish quite easily. The top mount is good I believe for about 350 but your injectors would be maxed out by then.

if you fit larger injectors on the standard map it will run less power as it will just run way to rich.
biggest problem will be that intercooler and the map.. the RA intercooler is the same as the standard one if I remember correct..

im putting this flywheel in next month when i change the clutch..

The phase 2 yellow injectors are 440cc btw.
Water temp cooler or EGT?

no the fuel pressure in the rails will be regulated to standard pressure if you have the standard fuel pressure regulator on there. 440 injectors is not enough to lower the fuel pressure by using lots of fuel out of the rails etc..

are you actually going to get this crate tested? if not why are we all guessing?

Not only are the injectors making the car rich when open loop, but there is a possibility of the 255 pump overpowering the regulator and making the car run richer! you may well be getting similar mileage due to the previous chip running the car rich also! Also if most miles are done closed loop then the ECU should be able to adjust fueling to get decent AFRs irrespective of larger injectors.
Personally I'd refit the 380's untill you get the funds for a remap. I think a decent remap should get you low 300's
