Ok so bare with me when I try to learn this. Did an ls swap & used an 02 5.3 dbc. Installed a btr stage 3 truck cam 218/224 .553/.553 110lsa. 2800 stall, long tubes, 3in dual exhaust. I spent a week after the install waiting on a response from several tuners in my area who never got back with me. So ordered the mpvi3 & figured id do it myself. Waited a week for that but did not realize I would need a wideband (for best results) but my wideband wont be here for another week. I spent all night reading up on tuning but im lost. I just want to drive my truck. Im just looking to cruise, not race, and ive been reading this can be done without a wideband. It runs now but seems extremely rich. Occasionally starts to misfire. Can someone point me in the right direction? Much appreciated
