Default fuel pumps

i know that hf crx's only have 45lph pumps where normal handa pumps are 70lph, my question is do 92-95 cx hatches have that same bullshit little pump? if so i think thats why i keep blowing up motors, with a conservative tune.

what xenocron is implying is that if the fuel pump wasnt keeping up, then the tune would be no good, because you wouldnt be able to keep fuel rich enough to to lack of maintaining fuel pressure.

engines can go lean for a number of reasons...failing fuel pumps is one of them. fully functioning fuel pumps is not one of them...

best thing to do...if you hear marbles in your engine...LET OFF
