Hello Folks.. Would like to hear from CTS or CS owners who use them on 04-08 trucks. They only come with custom tunes. Unlike other folks here who have fiddled with their edge evolution and are happy with those settings that suit them. I have managed to change WOT fuel, timing, shift firmness, rev limiter. It even allows to adjust T/C lock pts but doesn't have an input for WOT shift 1-2,2-3,3-4 in terms of RPMS. It goes by mph. The edge guy says to just keep the same -3 or -4mph value that you set for T/C loct pts. Would like to see if any of you have a different setting other than that came from EDGE.

UPDATE - Filled 91octane and set it on Level III, firmness 18, am seeing if go to 20mpg, avg 18.8 hwy. That's impressive.
