Hey all! I'm new to this forum and new to the Titan world. Love the truck, have the baseline model with 82k, just got it a week ago for $9,800. I want to get the best bang out of my buck, it has way more power than I need, and am looking at best gas savings mods including a tunable "chip." Gas savings may include non motor mods if you know of any. I was curious to know how the "tow package" works after you tune or piggyback the ecu. Does it overwrite, or modify current maps? Are you best of with a exhaust temp sensor or without? I would like to tune the sensitivity of the throttle it tends to be very sensitive the the lightest pressure. On the fly maps are not neccessary but would be nice for the chode at the light that thinks he's a bad-axe. What are your ideas, and what kind of results have you had? Thanks!
