s40 t4 p1 injector upgrade

[weemo1rush]

Hello chaps.
OK I'm after a few pointers. I have a mild modified s40 t4 p1. Exhaust , Panel filter, actuator adjusted.
I'm thinking of an adjustable fuel pressure regulator. And some new injectors I've been told that bosch reds work well for un upgrade from standard greys.
Any of you guys done similar?
Regards Davo

is this the cheeky little mod ive heard of popping the small clip to turbo and winding out the nut?
