Ok I have a 91 crx dx converted to mpfi. With a DOHC ZC. a t25 and a smic I am using ghettodyne for fuel and ignition. Every time i get near 0 vac i go dead lean. I have tried alot of maps some so rich it shouldnt run. Same problem everytime. I DO make boost but the AF gauge will go dead lean.

I have replaced plugs cap rotor wires and Fuel filter. Lets hear them idea's folks. NO I dont know my fuel pressure...

I can supply the bins for the tuners to look at at request.

Mine does the same ---- at 1/4-1/2 thorttle and also at or around 0 vacuum or boost. I am not worrying about it becuase A/F gauges aren't really accurate.

get yourself any pressur gauge at the junk shop to see whats the pressure you are haveing on your iinjectors.
then whats the sice of your injectors?
Maybe at that moment you are out of fuel
maybe you need a extra fuel pomp
