You guys have to rev to 2500RPM? Stop revving so damn hard!
I only rev my coon to 2500, maybe 3000RPM if I want to go somewhere f**king quickly.
Otherwise, keep her below 2000RPM all the way, cruise at 100KM/H smack on 1500RPM... And it pulls hills at that
Oh, and freeway does 8L/100KM with 4 adults cruising at 110 - 120KM/H, with a few hits here and there.
