Hey guys,
had walbro 255 gss342 installed today to replace stock pump
all went in ok.
only thing is it seems to slightly hesitate just after a gear change when I go to accelerate.
seems ok on full boost, but can slightly hesitate when I go to accelerate.
now when I say hesitate, its not jerking back and fourth, its just not responsing to the amount of acceleration im giving, then all of a sudden it will go back to normal
not sure if a swap in pumps could cause this.
its running stock boost, fuel filter hasn't been changed
no tune has been done, and car was running very lean before pump went in.
NEED HELp ASAP
