Mo'boost means alsa mo'powa. unfortunately increasing the boost requires to increase the flow of the juice.

I'm on my way installing cold start injector from the Saab K-jetronic. That should be good for another 30hp. Original idea was to drive it with another hoobs pressure switch, but i came with another fantastic idea. Since Audi S4 boost solenoid valve is just a dummy valve operated with magnetic coil, just like the extra injector is.. Why not to connect extra injector to original boost control wires? When ECU want's to cut the boost, it will actually spray more fuel on the fire! WHOHAHAHA more fuel is delivered and no worries with the lean mixture.

safe and reliable 280hp and 30$ saved because no need for pressure switch

Yes, just use a tiny injector and it will be pinned open during on demand, but very lame control of mix. Could also wire the horn to the extra injector, tilt the steering wheel toward one's groin, and hump more fuel into the system.
