Quick background, I have a 2002 Z28 with K&N Cold Air Intake and Flowmaster catback exhaust. This past weekend a buddy and I put BBK longtube headers and BBK ory and then tied into the existing flowmaster exhaust. So now there are no cats and i only have 2 of the 4 o2 sensors hooked up.....what do I need to do to get it tuned right? It sounds like its running way rich, makes it sound almost like theres a cam in it but theres not. I have a Diablosport tuner, just dont really have any experience or knowledge about tuning. Any help is appreciated! Thanks
