If you own a Dodge with a Cummins Diesel, you need a Smarty Programmer! Ask any true diesel enthusiast with a Cummins which programmer makes the most power, has the best tunes, and gives the biggest increases in fuel economy, and they will all tell you the same thing – Get A Smarty!  Your Smarty Programmer for your 1998.5 to 2002 5.9L Cummins 24V comes with ten different software settings. The power gain at the top Rpm with this software is almost identical. This software differs greatly from how they get there. The higher the software number, the more aggressive the throttle response from idle speed up. Aggressive to the point that software Eight and Nine can become difficult to handle on slippery roads. Please be very careful when you use this software for the first time! It takes some time and practice to learn how to handle them.

Smarty’s Software Levels

  • Software # 0 – The half-power setting is useful whenever reduced power is desired or when you have to make sure that no smoke is produced.
  • Software # 1 – This fuel saver software produces average fuel savings of +2 MPG! Heavy Towing is not recommended with this software due to the aggressive nature of the tune.
  • Software # 2 – Increases fuel delivered by the ECM and includes boost fooling
  • Software # 3 – Same as software # 2 but timing has been added.
  • CaTCHER Softwares # 4 to # 9 – The even-numbered software is identical to the odd-numbered ones, except for the timing. The software without added timing is intended for use with timing adding boxes.

Many customers ask “How much horsepower will the CaTCHER software add to my 98.5-02 engine?” The short answer is that it depends on the mods done to your engine. On a stock engine, typical gains are 60 horsepower at the rear wheels. With upgraded injectors, the Hp gain increases. How much depends upon your injectors, turbo, intake, exhaust, etc. The best mod combined with the CaTCHER is a good set of injectors.  If you feel that you absolutely want to “stack chips” The CaTCHER stacked with a fuel-only box provides the highest Hp gain. More than what a timing & fuel box that can’t be stacked with anything will provide.
