While installing my stage 1 dynojet kit I decided not to block off the main air jets like the instructions said because I was going to get a flow commander. Well it ran like shit, is this because of not blocking the air jets? I have since switched back to the stock and am going to get the Ivans kit, hopefully have better luck with this kit>Anyone else not happy with Dynojet? Also is it just me or are there jets smaller than the stock ones? maybe to compansate the rich condition you would have got from blocking the main air jets.
