Midnight is the name of our 2011 Duramax LML test truck.
We plan on testing many products on Midnight, writing reviews,
doing install videos, and showing real dyno results that will
be posted to this section of our website.
Midnight Introduction: Thoroughbred Diesel purchased
a 2011 Chevrolet Duramax in the spring of 2011 for the purpose
of testing various product for fuel economy and horsepower gains.
The first 5000 miles provided a break in period in which the
truck was driven for daily travel purposes. No modifications
were made during this time; however, with the break in period
complete, it is now time for serious testing.
Once the truck is modified, it will undergo a series of tests,
unloaded and loaded with a 10,000lb. trailer. Dyno runs and
hand calculated mpg results will help evaluate the fuel economy
and horsepower gains. This information along with our opinions
as to the pros and cons of each product will be shared with
you, our valued customer so you can make an informed decision
on the modifications you would like to make on your own truck.
Specifics of the 44 mile test drive includes:
driving; avg 70-72 mph
town driving with stop and go conditions; avg 55-60 mph
mile long hill at a 4% grade
runs will be completed in house at Thoroughbred Diesel on
