[urq] EFI + MAC-14 maxing ataround 5k RPM

[Cody Forbes]

37lb/hr times 5 cylinders = 185lb/hr total.
185lb/hr divided by 0.55 BSFC = approx. 336hp worth of fuel at 100% duty 
cycle.

You are looking at injectors barely good for 275hp in safe duty cycle 
ranges.

That said, injector sizing is **NOT** your issue with no load on the engine. 
It is however a big problem on the road at even mild boost levels.
