exhaust pipe diameter is too large

assuming 3000 rpm as approximate upper ceiling of cruise , your exhaust pipe diameter is over 200% too large ,
and it does matter
begin here Autolounge.net | Calculators | Exhaust Pipe Sizing

then
read this thread http://ecomodder.com/forum/showthrea...mpg-12247.html all of it .

the MPGuino will help immensely as well
