Not sure what you mean by resolution? You run a larger mass air flow meter to get more air to the motor. Combine that with more fuel via larger injectors and you create more horsepower. With a piggyback fuel computer like an AFC or AFR you can fine tune the signal and dial in the proper A/F ratio easily.PSiedSC300 said:Just as a question, why would you want a bigger MAF? You lose resolution with a bigger MAF, so wouldn't you benefit more by running the smallest MAF possible?
