Wife & I never watched drag races because we were too busy racing our cars. I've never blown a motor ever. My thought is whenever a manufacturer gives the weight limit it's not at it's maximum limit, not like if it's rated for 1800 lbs. it breaks at 1810 lbs.
If I can work the tractor at 1700 rpm instead of 2700 rpm, not spinning the tires getting the job done if anything engine will probably last longer.
Any questions...call the company that designed it. If installing that module causes engine damage how can they stay in business?
