Tuning It Up
With all the power modifications done, tuning this beast
turned out to be somewhat of a challenge. The tuner that
Anderson had on the truck with the twin turbo setup was
not working very well with the triple turbos. To fix the problems they were having, Underground switched to a Smarty
SSR tuner. While that made a big difference, the injectors
were unfortunately over fueling the engine.
The issue came from using 180hp injectors as recommended by the kit. The higher capacity injectors were
needed to help keep up with all the power from the triple
turbos. Unfortunately, the Smarty SSR was supplying too
much fuel and Underground was unable to cut it down.
In an effort to find a better solution, Underground
switched out that tuner for a Smarty S06. The change was
just what they needed to get the fueling problems under
control.
���It brought the fueling back down where it needed to be
and it runs really good now,��� says Tolf.
Even then, the truck is still not fueling as well as the
shop would hope, as it still smokes more than desired. Tolf
hopes that a version of the EFI Live that comes out with
support for 2005 Cummins will allow them to reach the
perfect amount of fuel.
Currently they are running the truck on either the number six or number seven tune (out of ten) with the Smarty
S06 so that it runs great as a daily driver. On a higher tune
though, Underground was able to pull over 900 horsepower
on straight diesel fuel and no nitrous. That is an impressive
feat to be sure.
���A lot of people think using injectables is cheating,��� says
Tolf. ���We like to do good, solid numbers that we know that
truck will make day in and day out.���
Hidden nicely in his tool box, the
nitrous system from Nitrous Express
was added to provide even more
power should Anderson need a
boost beyond
his triplets.

A Powerful Impression

You don���t have to be behind the wheel of a truck or
looking at dyno sheets to understand how much power the
triple turbo setup gives this truck.
As we stood outside the Underground Diesel Performance shop on a warm, sunny day, we asked Anderson to
do a power run to show off the exhaust and smoke the tires.
As he got on it, you could hear the turbos whistle and
exhaust roar. The tires started smoking and Anderson was
off like there was a rocket strapped to his truck. It sounded
like the tires never gained traction at all. One look after the
exhaust and tire smoke cleared revealed a strip of rubber
over 100 feet long.
And that is why this truck is so intimidating. Not only is
it full of attitude, but it���s going to get bigger and bigger
quickly in your rearview mirror. Your mind almost naturally
reacts by trying to get out of the way.
That is what we love most about the truck. It���s powerful
and unique, but has the attitude to back it up. It delivers in
all the ways that diehard diesel enthusiasts are looking for.
So if you ever see Anderson���s big, loud blue Dodge
Cummins rapidly approaching in your review mirror,
watch out. DT
