Progress is good, being from the older days, never liked the computer age anything BUT I have learned the new way ain't so bad. My ISM500 runs great for 112,000 miles so far, uses no oil at all and gets nearly 9 mpg depending on how its driven.
The new DEF engines can go way up HP wise due to the lack of emissions due to the DEF sprayed into the muffler , so the HP can be turned up a lot and still satisfy the EPA.
Do not for get back in 1925 Rolls Royce was the greatest engine ever cause it could go 25,000 miles before needing rebuilt.
We came a long way baby.:)
