Hello I'm new here and need help & advice. I own a 05gto w ls2. I recently installed a cam, zo6 heads, headers, exhaust system. The car gets random misfire codes pretty regular. I need to knowif I need tuner. I have a plug in superchips model, but can't do a lot w it other than delete dtc. I am interested in buying a set up I can tune & learn. Only for my car. Will be doing lots of mods.
