ESS G2 Start Up Issue - 2015 Mustang GT

[5doorsoffury]

where on the island was this guy? is he a speed shop or a buddy? what did the car afr register before it died? did it smell rich? if your injector data isnt spot on it will run like shit, afr will never settle ect... you dont have any vacume leaks? if it were me i would swap in oem injectors, load up the oem tune and see if it runs ok without boosting. if so then the issue is the injector data in the new tune

This is probably not a tune file issue—if stock tune and injectors yield the same result, it's either fuel delivery, idle air error, or sensor logic fault. Eliminate these before returning to ID1050 base calibration.

Dont try to start it with the stock tune but the 1050s installed. That wont work either.

Hey !
appreciate all of the suggestions, I went with Wengerd Performance, as I triple checked everything on my end. I was competent enough to do this job myself and behold! It was the Tune. The tuner was a speed shop in long island; he was doing a remote tune for me through VCM scanner and suite. After going through 17 different tune files, he said “I gotta see this car, tow it to me” and thats a big no no. So I called the shop itself and explained the situation with a reply of “i charge $150 an hour to figure it out”
I hung up and went to Wengerd performance. The guy sent me ONE tune, the car started right up. But now, the last tunes destroyed both O2 Sensors before the cats, from running so rich. I’ve attached the O2 Sensor. A literal piece of charcoal. Note to self, buy cheap, buy twice.
THANK Y’ALL FOR ALL OF YOUR HELP!
i will update once the new O2s come in.

“ i’ve swapped out to stock injectors, started it with stock tune and still does the same thing.”

This confuses me then. With stock injectors and stock tune then it wasn’t the tune. There’s a bit of a gap here.

Sorry!
i have the BAP and upgraded fuel pump as well, that would explain the stock tune not functioning properly as well!

Update, i’ve swapped out my O2 sensors, the issue still persists
