Congrats and good luck with your new MADP> I have an 02 MADP and they are nice, quality units. It will have bugs to be worked out, but with time it gets almost perfect. I assume that you lose speed on hills is because it's not broken in, My unit maintains same speed ,towing or not, but I always use cruise control,which lets computer do whatever to keep speed constant.
I have always used synthetic oil in all my rigs, better constant viscosity, runs cooler, improves performance etc. Yes, it costs more, but you have a $300,000 plus investment here so whats an extra $100.00 once a year or 18.000 miles, ???? 400 hp ,Cummins ISL. I started using synthetics at 3,500 miles, engine and transynd in tranmission.. Less friction, less wear..
Again , GOOD LUCK and happy motoring..
Thanks---- AJBJRVERS
