Default Dealership Bricked ECU

Hey all,
This past December I had picked up a 13' WRX Hatch that I assume to be was running stage 2 as a certified car from Shultz Certified in Pittsburgh. Everything with the car had been amazing (don't need to hear about buying a tuned car it'll have a roll cage and be a track car when i can afford a secondary).
My battery had gone bad when I was visiting my sister in Canada, when i got back it was reading 1.9V. All was perfectly fine until this moment, scheduled a appointment at the dealership to have the stock exhaust thrown back on due to noise complaints with being catless with headers in a smaller town in Vermont.

Was not really a fan of the idea of having them do the work for free as I really didn't think they seemed qualified to be doing the work and tune in order for it to go back to stock-ish with the mods that are still currently on it. Well turns out when they swapped back to the stock exhaust I ended up getting a call from them saying they pretty much fried the ecu, and were sending it out to Cobb for them to rebuild that and the V2 AP. Car has been in the shop for over 11 days now and I'm really not happy with them and how they've handled it. any advice on my end would be greatly appreciated, does going back to the stock exhaust after running a tune for so long eventually cause problems?

When the battery went dead is when I started seeing all the trouble with it, Threw a p0134 CEL, traction control light is currently on and cruise control was also illuminated constantly when I had brought it back to the dealer in Pittsburgh.

Why did you have a dealership whose mechanics you dont trust do any work on your car, and why was the work done for free?

Does Vermont even have a Cobb certified/tuner tech?

not that i am aware of, VT sports car does all the subaru builds for rally racing in Williston. This will most likely be who I take the car to for future work when I decide to take it back up to stage again. Looking in the area, Im in pittsburgh as of right now because of this issue. Ill keep ya posted on what the dealer does. Not thrilled and learned my lesson with it for sure.

Well it's a bit of a drive, but EFI Logics and The Shop CT do some good work.

Alright so finally got the car back from the dealership with the stock exhaust from turbo back. Boost seems to be cutting around 5000 RPM at about 3/4 WOT, lugs forward and won't do anything past that really. Running headers still, Grimmspeed TMIC, Grimmspeed boost solenoid. Thinking because it is back on the stock tune it is acting and not having the best drivability. Car gets incredibly jumpy if trying to go past 5000, it'll drop down in boost then come back and repeat that cycle if trying to go over that rpm.

Question for anyone whose gone back to stockish, did you have problems like this? and im assuming a Protune will probably be the only solution. Many thanks

If you want to run the stock map the entire car needs to be stock, that means headers, intercooler, boost solenoid: everything needs to be stock.

If you want to keep the headers, tmic, etc, then yes a ProTune is your only solution.

Thank you for the reply, making an appointment with TPG Tuning in the morning. Thats what i figured and just needed some re assurance. First subaru and definitely not the last one. All of you have been a good help.

Meh, headers and intercooler? Probably fine. The EBCS is the problem. Either take it off and go back to stock boost control, or get the car tuned for the EBCS. The engine MUST be tuned for the EBCS.
