pinks on newage can make 380 bhp and close to 400, anything above look for 650cc or 750cc ..

The pinks will be running about 85/90% duty at 350 hp so they are usable.

Ok. The last thing I want is to run 350bhp and the injectors cant cope.
I might just upgrade to 650cc to be safe.

Since you've already got pinkies installed, it would be easier and quicker to fit an FPR instead. raise the pressure by 0.5 bar and you will be safe into the 400 hp area.
