Does anyone know the speeds at fuel cutoff for 2005+ Boxsters (non-S) with both 5 and 6 speed trannys? And/or does anyone know the rear axle ratios for 2005+ Boxsters (non-S) with 5 and 6 speed trannys?
The speeds are mentioned in my 2002 S's manual, so I'd guess it should be in your manual as well. Look for it near the back, in the Appendices I think.
