I have 3.43 diff in my 130 and find it just perfect. this would make the 1M even more raw.
Not sure I understand you. You can't compare a 130 to a 1M. The 1M's 6th gear has more than adequate passing power and is very useable. It is so useable in daily driving to the point where you can skip 5th. I wish 6th was more like an overdrive to improve highway fuel economy.
