Took the plunge, Bought a 2010, 6. 7. Had a 04 with the Smarty Jr. Waiting to get the hitch on the new truck can not wait to pull the toyhauler. Question : I had a X-monitor for the 04 and liked the digital part and ease of install Has anyone tried the Glowshift ? and what tuners leave a tracable foot print and do any of them not leave one ? Is it worth the cost to get a turner with the gauge setup all in one ? Thanks for all the info of the past you guys are a great help.
