0 j_martell Posted February 17, 2018 Share Posted February 17, 2018 ....maybe thats were the cut off is set. My "old" 2011 MP7 granite was 900RPM and the PowerLeash de-activated. the RD doesnt have an engine brake Quote Lack of planning on your part does not constitute an emergency on my part....

0 Natedog Posted September 23, 2019 Share Posted September 23, 2019 My e6-350 engine does the same thing, works well until I get to 1200 rpm, then stops working. Did you ever figure out why?
