Car currently 380bhp before i fit stainless headers,fmic and get my motecs remapped i know my current injectors are holding the car back now b4 i fit the new goodies but unsure whether 550cc or 740cc is the best size to go for...
I'm hoping to break through the 400bhp mark but no real desire to go beyond 430ish...(at the moment anyway)
Any Advise greatly appreciated in advance

In my experience 440s will go to around 350 bhp, 550s are close to maxing out just over 400 bhp and 740s are all done just below 600 bhp. Increased fuel pressure will allow a bit more.
Only approximate figures which will vary, engine to engine, fuel system, ECU and means of measuring.

My std 440s are about as far as I would like to take them with 340bhp.

For 430bhp I would want to fit 740s.

Harvey has been there and done that so I would take his advice.
