Hello, need some help to make sure everything looks good and if I should change any settings. Normally run map 1 with 91 octane, but recently filled up the car with 4.5 gallons of E85 and a full tank of 91. 2022 Stinger GT2 RWD, only have a catback exhaust and k&n drop in filters along with an occ. Thank you!

Fuel trim looks high, do you get any stutter or backfire at high rpm's ?

What would cause that? For the first couple of fills I only put 4.5 gallons of e85 and a full tank of 91 but lately been putting 5 gallons instead. Haven't noticed any backfire or stutter, car seems smooth and powerful.

From what i have learned high fuel trim mainly from a vacuum leak or exhaust leak .

At the time of that log, I had installed a primary and secondary downpipe and has a small leak between the primer and secondary and possibly where it bolts at the turbo. I since went back to stock and put a catback on instead.

Would say good chance your fuel trim is good now.
 
More than likely your Trims are high because of your high E content. Your timing is fine so no need for 5 gal, you don't need that much Octane for map 3. Drop it back to 4.5 or 4 and that car won't struggle to keep your AFR (Trims), you run the chance of getting lean code.

Understood, will lower E content on my next fill up and repost a log.

Why not run 93?

Several states do not offer 93, like California, Arizona, Colorado, Idaho, Oklahoma, and about 20 more. They only offer 91 as premium.
