Still recall my first few weeks driving a “stoichemetric” Mack ! The thing was a complete dog out of the hole ! If you needed “power right now” you had to keep the rpm up in idle. The dog burnt as much - if not more - diesel than earlier models doing the same work ! >PS

Macks really ARE horrible "dogs".

E-tech engines are the worst. The MP7 seems to be a little improvement, but they will never be as good as the old E-7's.

What year and and model are you driving?
