a 190 will push the 450cc injectors, thats no problem. but it will be pushing HARDER than a bigger pump. so, your injector duty cycle will be higher, and the amount of Fuel Pressure you are running will put strain on the 190 pump.

now with a 255, the fuel pressure can be lower, and the efficiency goes up of the injectors and the regulator. less prone to dieing out.

you can put a 255 Fuel Pump on a STOCK CX motor, it wont make it run more rich, the FPR is what controls the fuel at the rail. that determines how much fuel you have. not the pump. it just means you can run lower FP and get the same spray pattern and a lower duty cycle=longer injector life

imagine if your mid throttle on the bottle and the fuel pump fails :gasp:

Good point ..So i can just drop a 255 right in and it wont change anything?
