2017 BRZ
Was tuned on E85 at 1K miles.
AVO turbo with larger injectors and upgraded pump installed around 5K miles.
This has been on for about 2K miles now.
All tuning done by Delicious.
Only anomaly has bee around 3 times since turbo install on start up the MAP is reading 52 inches at idle. A couple of restarts have cleared it. AVO has not stepped up yet to replace MAP sensor.
New problem
Finally took a long road trip just under 300 miles instead of my usual commute of 19. Was able to keep E85 in the tank on the entire trip. After about 200 miles at cruze the engine stumbled/cut out a couple of times. This was followed by a check engine light. However it did not take out the cruze control. This light turned off and back on a couple of times. Pulled off to get gas and no trouble codes were stored. Went to start the car after filling up and it immediately died. Then the next start was good. This issue came and gone a couple more times on the rest of the drive. This also happed a couple of more times while in Austin for the weekend. Along with the engine dying immediately after startup.
Sunday morning getting ready to drive back I hooked up my computer to catch it in the act. On start up this morning it threw a hard check engine light. Codes P0171, P117B, P1170. I cleared the codes and keep the computer hooked up and started driving back. No issues at all after 3 hours or so and 1 fill up. Shortly after computer battery was almost dead so I shut it off. About 15 min later with cruze control on the car stumbled and the check engine light came on. I did notice on my wide band AFR it was jumping from 13 to 17 or so instead of the usual 15 +- .5. This continued for about a min then the light went out and AFR stabilized. Never took cruze control off. No issues the rest of the trip.
I love these intermittant issues that you can not catch in the act.
What are your thoughts? How many issues are there that will cause the check engine light to come on with out killing the cruze control and will clear itself?

DANG, Grady, you're using E-85, you put in larger injectors, you installed a turbocharger, you had it tuned ........ then you head off on a long road trip .... and now you are wondering why the engine is bitching .......??
Well, you did ask for my thoughts .....
