If you want some info on obd0 tuning, I'm pretty decent with turboedit, and I can help you in the right direction. You'll want to get a socketed pm6. Where are you located? I could help you out if you are anywhere near central california. I have a wideband, laptop, and a moates ostrich so you don't have to burn chips while tuning. If you don't live in Cali, go onto pgmfi.org and register a username. Then start reading up on turboedit. It's all opensource right now, and I can give you a working copy of turboedit for you to play around with.
