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.

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.
