I see - okay - so the house tune was the actual tune and the ECU work ? got it - like I said i'm sort of new - I know a little about a lot - not a lot about a little.

Am I understanding you correctly now? So the accessport wasn't the ECU work? but rather a code clearer - a map changer and some other things? Am I picking up what you're laying down? I'm still learning a lot. SO much to learn w/ these things.
