Farmers!  We definately haven't forgotten about you, and neither has Western Diesel!  These modules will also work in JD combines using the above stated engines, or a EDC Injection pump with GM 6 pin connector.

• 55 hp increase
• Easily installed on any John Deere piece of equipment with the Bosch EDC injection pump.
• Even though you remain at the same fuel usage level, the extra power will pay for itself in better productivity.
• Sold by John Deere dealers and diesel fuel injection repair facilities around the country.  The power added by the module is not a threat to your engine's performance.

We are so confident that you'll love the power increase of the module that we offer a 30 Day guarantee.  If you decide the tractor module isn't for you, just return it in "new" condition for a full refund.  No questions asked.

By the way - We haven't had a module returned yet.
