Everyone has been super in giving answers to my questions, however I still have another. I have added 4in exhaust, ripped out the air snorkel, have a K&N filter. I have been reading a lot about bumping up the pump. With the added air coming in and going out will bumping up the inj pump help? If so how much should the pump be bumped up safely? I need all I can get in HP with the least ammount of cash outlay at the present time. Thanks gordon.
