What I assume is "limp mode" issue. Not solved info in post #1
Ok nothing is solved so let's start fresh.
*new info* Car runs like a champ with MAF unplugged, issues are only with MAF plugged in. MAF and ECM have been replaced, original ECM is back in the car as it saves me $$$
It HAS to be something the MAF is affecting but I can not for the life of me figure out what it is...
Subaru had the car for 3 weeks and the only idea the tech line gave them that they didn't try was oil control valves. *new info*
Ok long story short I flashed Cobb stage 1 and this arose, tried many things and the issue remains.
Car runs perfectly up to 4500 rpm then it just hits a wall, feels like fuel cut or hitting the rev limiter.

I have tried flashing stock map, flashing stage 1 again, completely removed the AP from my ecu.
New plugs
New fuel pump
New fuel filter
New bcs
New MAF
New battery
New MAP sensor
New front O2
Disconnected battery for 12+ hours.
No vacuum leaks of any kind.
Not one CEL.
The problem persists unchanged.
Yeah if it's free, it's not a big job that they could really mess up so who cares (famous last words).
I'm just really curious how exactly they went bad. It's really really unusual since they're just a bunch of metal with precious metals embedded in them. Not much to go wrong, but it can happen. It's always due to much higher than designed EGTs in my experience in tuned cars.
These cars normally run ok without the cats, but sometimes they don't. It's been known to happen plenty of times. I hope it's not the cat in the uppipe that went right? It's the two in the DP/catback exhaust?
Ok now they're saying it's the uppipe since the two got replaced and it didn't work. How can that even be possible? It was replaced last year and there's not even a cat in there...
That created no problems, I tried something and it didn't work so I put it back. The dealership had it for 3 weeks and couldn't fix it, I'm going to have to figure something out.
You said you must have done something wrong when you flashed, causing problems. Then you did another mod incorrect and got more codes. Glad you got those fixed. I don't understand what you're saying..... Who knows what could be wrong at this point depending on what you did wrong when you flashed.
Something doesn't sound right...... I need to think on this a bit more, but if I were you, I'd find a REALLY good tuning shop near you. Any chance you can take it to Cobb's workshop?

Shop still has the car, fixed some minor problems but it's still the same. Best I can figure is maybe the previous map was to compensate for some mod that none of us can find.
