Hey y’all iv got a 2016 w900 with a 2015 cm2350, currently the truck gets horrible fuel economy has no power and just simply unreliable. I’m a one truck owner operator and just can’t afford
This type of mpg and down time. I’m looking for a good safe tune geared towards economy and reliability. Ps I have done a egr tune up on the truck. Thank you for any help it is greatly appreciated.
