so lately i've been having issues with my car, any time i would go up hill or accelerate to fast it would fall right on its face. i logged it one day with nistune an saw the afr's go full lean plus i had just burned out the walbro so i put the stock pump back in.. so fueling issue made sense. so first thing i got the hookup on another pump from Keo (denso supra turbo pump) but to be sure i replaced the fuel filter first which had no effect. then today i installed the denso pump and all is well in whosville
