At what power does the stock fuel system start to become an issue?
It's difficult as there is so little information from the UK, and most US dyno numbers just do not make sense to me, As I beleive above 450bhp (crank) the LPFP needs to be addressed and above 550bhp you'll need to replace the HPFP or run PI, would these figures be about right?
So if the OP is only looking for a moderate lift to, say around 450bhp and the turbo's need replacing anyway, would it not make sense to have the turbo's modified instead of running stock turbo's outside of their efficiency range?
