February 2023, I purchased a performance module for my 3L EcoDiesel. While I was a little skeptical at first, the owner, Allan assured me that he would refund my money if I was not completely satisfied. Well, I have to say I am very impressed with the improved low end horsepower. Not only that, I’m up 3 miles a gallon “at the pump” making it a great investment. In fact, I am so impressed with the module’s performance, I bought another for my brother for his 5.9L Cummins. Thank you for a great product.
