how do i check them to see if there is something wrong? i got my fuel pressure down to 39psi and im still running rich.

 

help me!!!

 

Your resistor box has nothing to do with how much fuel youre getting. What are you using for fuel management?

 

im using the neptune p-28. it has been set up for 450s

 

???

 

bumpy cause I run 450's on uberdata and I run rich as hell, then sometimes it magically really leans out for like 30 seconds and i can't give it gas. I know it's leaning out because i have a wideband (plx m-300).

Is this a 1.) Injector 2.) Resistor Box or 3.) Uberdata problem

 

whats your fp at?

 

hmmm
