My speed is closer now than it was before my tune. I told them to adjust for my gears and 33" tires. There's definitely a change and I suspect once I go to 33's it will be on target.
Did folks get their PCM tuned or get the core package? I got the core so I'd have a spare. Maybe it's easier to correct in the older models?
