A 5 hole by 0.0085 is about all a non-modded CP3 can fuel. Injector size is limited by available rail pressure. A 5 x 0.0105 with a CP3 mod kit will make about 700rwhp, with electronics and other mods as well. A 280 would make it through about half of first gear before rail pressure fell off to around 8k psi. It would feel like you turned the key off!
