Finally, I had everything ready for some seriouse tuning and for dyno. but the guys at the shop told me that since I had an engine light on, its better that I fix the engine light first. They offer to fix my wirring for $250 before doing the tunning. I am not an expert on hooking up wires and I had to admited that my wires wont looking good, but at least my car runs, only the engine light on. the engine check is traced to an O2 sensor. What do you guys think, should I go ahead and do the tunning with the engine light on or fix it before doing it. thanks....check for my signature for mods if interested!
