Why do you want to change the injectors ? the standard ones are good for 290-300 bhp (BTW they are 380cc not 350cc) . Are you running an after market ecu to take advantage of the bigger injectors ? if you are then it can be mapped to take out the extra fuel at the bottom end .

The problem i have got big bear is i am running a sti block with uk manifold and ecu ,big turbo, mongose ex, cone air filter ,super chip ,car ok in summer but in winter it pinks on full throttle, i think this is due to cooler air being denser and i dont have enough fuel goeing in as proved by air fuel meter,boost pressure is 18psi which wont go lower due to wastegate hitting against down pipe ,was told a twin downpipe sold buy power engineering would solve this but would rather keep boost same and add more fuel so car keeps same performance

I see your problem now , you may not need injectors . You may be able to get away with an AFR , this alters the signal between the airflow meter and the ecu , HKS and Apexi both make them . Try www.tdi-plc.com they may be able to help you out , if you still want bigger injectors they may also be able to help you out if your engine is a phase 2 type .
