Ok guys, debating on whether or not to spend 600 bucks on the edge evolution cts2 programmer (https://www.carid.com/2002-chevy-ta.../edge-evolution-cts2-programmer-72762753.html) have a 2002 tahoe LT 5.3L with 35s and a six inch lift, will the economy tune actually increase my mpg any higher than the ****** 12 mpg it already gets, do a 140 mile trip once a week so thats my main reason for wondering.
