Has anybody bought and installed the 91 or 93 MarkD chip on their M42?
What results are you seeing on a dyno? Or at least a butt dyno?
Any side effects noticed? Fuel economy? Idle?
If installing this, would a tune be necessary afterwards?
Clearly thinking about doing this on my ride, but want to know what people are getting from it already first.
