Thanks for those suggestions. Iāve already run a couple tanks of 93 through it after running the regular down to fumes. Getting close to 2,000 miles when Iāll do my first oil changes. Iāll disconnect the battery that weekend overnight. I hadnāt thought of that.Honestly its probably best anyway to get that first tank out of the way and get some break in miles on it, so it wouldnt much matter to start with. But I'd run that first one down to fumes. Then a complete 93 fill up. Then give it about 20 miles or so to get all the lines clear of the 87 and pull the battery cable off and let it sit overnight disconnected as to get the long term fuel trims to clear. This is also called a KAM reset. Then next day hook it back up and go for a ride. That should get you about as clean of fuel trims as you're going to get for that density altitude.
