2019 A10 mustang on E85 Lund tune.
Car turned off at highway speeds today; was cruising ~85mph and got on the brakes due to upcoming slower traffic. Car downshifts from 10th to 7th as normal, but then turns off when I reach like ~60 mph 0.o
scared me since there was upcoming traffic behind me (always paranoid about getting rear ended), but I was able to throw it in neutral and turn the ignition back on and kept going like nothing happened.
Car didn’t drive noticeably different after. I haven’t ever had this happen at highway speeds although I have had 1-2 isolated episodes over the past year of ownership but it happened when idling at stop light.
Aside from E85 tune, just cat delete and aftermarket exhaust but otherwise stock engine wise. Oil changed ever 2.5-3k miles (just changed 400 miles ago) and I get gas from the same Shell station that always tests E80%+
No codes; but wanted to get any ideas as to what could be causing it? Would like to take it to the dealer eventually although tune may limit coverage
