swaping '95 4.0 FPR?
i have a chinese version 95 4.0. i think it more or less the same with the one in US
the question is if i change the FPR from stock(#53030001) one to a 43.5psi FPR
will it change the MPG or power?
thanks.

more power? not really... the computer tries to keep the air/fuel ratio constant, and the amount of air in the combustion chamber is fixed so the only variable under control is the amount of fuel. Jeep computer doesn't care about more power it cares about proper amount of fuel.
If you want more power you need to increase the amount of air (larger chamber, or forced induction), or reduce the amount of drag on the power that is already being created
