The Challenge

The Case 8120 is a common machine. However, they are often under powered for the jobs owners are putting them on. Clients often just ask for more power, but we can do even better!

The Solution

After having the ECU tuned by Alt Tune, the customer gained an 8% fuel saving, 25% better capacity due to increased ground speed and the ability to maintain engine RPM.  That’s a massive 33% improvement over the stock machine, resulting in some huge savings for the customer in both fuel and increased productivity.
