uh, you guys still didnt answer his question! he asked if he could use the fpr with the fmu to help lean the fuel out..you can just use that! use the fmu and with the fpr adjust the little bit of extra or less fuel you need. ofcourse he can use an adjustable one but its better to work with what you got or what is less expensive...

 

i already answered his question, and since he doesnt have the fpr, that would be more money he needs to spend...even with the fpr, the fmu is still rising at too high a rate and theres not much you can do with the fpr other than change the base psi i think
