I just installed a Smarty tuner on my truck and I really do like it but I would like to see if I can notice any difference between the Smarty and the XRT. I don't have the money to just go buy an XRT. If anyone has an XRT and would like to try out the smarty let me know and we can meet up one afternoon. I've seen claims of guys with the XRT getting over 20 MPG and the best I've been able to get is 17.2 MPG with my smarty. I would be interested to see if the XRT would net me better fuel economy.
