Hey guys, I am getting exhaust sputter when I let off the gas. It only seams to happen in the middle to low RPM band. I do have a catback exhaust. I know that our cars run a little rich stock. I just installed my Walbro lph fuel pump also, but I cant rem. if it was happening before then Just curious if I should be worried. Maybe the turbo install on sat will take care of it TIA Nick 97RS
