I recently started having a problem with what seems like a studder or surge only in 2nd and 3rd gears under moderate acceleration. I have been told that the timing may be advanced too much. Under full throttle acceleration everything is fine. The only mod on the car rite now is a 255 walbro pump and a K&N filter. I would like to get this resolved because I am getting ready to install a P1-SC and 3 core intercooler, along with some bosch series 3 -39# injectors and a pro-m calibrator.
