    Doubling the fuel pressure is not the same as doubling the injector size.

    Dont listen to what everyone is telling you. My ECU was for siemens 80s to and It was SO rich I could not run. Tried siemens 60s and to rich as well. Tried bosch 55's perfect and my ECU is a 9.5K les cooke. Bottom line is before you start swapping stuff and finding new injectors try what you have.

    My base pressure is only 42lbs with these 55's and Im running 11.5 WOT @8950 Rpms.

    As long as you have an AFR guage go ahead and use the 48s and see how they run or else you may end up doing more work for no reason...

    Learn from my own mistakes.

    What ecu are you using?

    No ecu can get more fuel out of an injector once it gets near 100% duty cycle. My stock 2012 ski has stock injectors that are maxed out.
