I have 2014 v6 mustang, idle bounces between 500 and 700 when at stop lights, feels like it's trying not too die, also, when accelerating WOT, car doesn't downshift unless I take foot off throttle a little, just stays at redline. This happens around 100mph. Are their adjustmentsite I can make to fix this or do I need to send logs in? Data logging shows timing all over the place when idle is bouncing.

Is this a custom tune?

sort of, it is 91 race tune with a previous edit from you guys to subtract some fuel. (logs indicated it was running rich)
