I am a recent member and have searched the tdr for answers. I have checked the codes (with a scanner) and have the 1693 and 0216. I have read about cycling the key to pull codes but can't get mine to do so. any way I am thinking of installing a blue chip pump, big line pusher kit from vulcan, a carter or similar lp and of coarse gages inc fuel press, pyro, trans temp, boost, is there other gages or parts i should look into? THANKS FOR YOUR HELP IN ADVANCE.
