@Puffwagon you're a pretty good teacher! It takes a lot of reading and learning to be able to tune your own car, but it is worth it in the end. I've got a folder I've written down everything I've learn from Puff and from the forums from reading. You'll need a wideband, I have an AEM wideband permanently mounted in my car which I'm about to get the cable to hook up to HP tuners so I can log afrs. I don't have a Knock detection device but I would highly recommend getting something! With the tune that was on mine, you could hear the knock inside the car! My engine is forged so will handle a bit more abuse.
