This is a great product if you typically drive your truck in any mode other than NORMAL. I prefer ECO. Plug and play. Hardest part was removing the upper plastic steering column housing to get to the plug. Installed module, cranked truck, put truck in ECO, turned truck off, restarted truck and the module put it in ECO after about 10 seconds. Slava stands behind his products. The first one that required programming did not work, he sent this updated version for free. Great customer service.
