When relocating my PMD to an FSD I noticed I have a #7 resistor. Is there any benefit (economy or power) to changing to a different size resistor?

Bill H puts in a #7 R in his FDS so there must be a good reason, Todd did explain one time, but as the norm in 1 ear out the other..i`ll have to do something about that, maybe it`s the age,,, or the Viking Wife..!

#7 was for emergency vehicles only, and gives the most amount of power and fuel. words straight from Bill Heath.

Only way to KNOW which is best is to put your IP on a bench and test the IP, remember it is a calibration resistor, depending health of the IP you may need more or less resistor than the 5 which is the nominal 0 for flow change to meet the spec. purpose of different resistors is to get the IP to meet the test spec flow.
#7 resistor is good middle of the road, I ran a #9 which is supposed to be most you can run without coding I never saw much if any change with it over the 7, if you have a 9 run the 9, if you have a 7 run it, IMO I would not lose much sleep over what one was in your driver.

I now know why.
Not that it really matters, but I run a #7 also. No issues with it.

:iagree:The only reason I bought a #9 was becasue I was leaving my old FSD on the pump and the new remote one didn't come with a resistor. Just like TurbineDoc said, I didn't feel any difference in performance.

According to GMTDScantech #9 res. was a .35mm3 improvement in fuel delivery over a #6 res. I didn't notice the difference needless to say. Leo
