Still getting MAF codes after Replacing MAF sensor

Maintenance/Repairs

I just bought a 2005 legacy outback XT with a swapped 2.0l engine and some small mods. T also came with a tuning chip that I’m not sure is helping or adding to the problem. Everything was fine except the maf sensor and air intake temp sensor were throwing codes. It wouldn’t idle for more than a few seconds without killing the engine, so I drove with it unplugged until I got a new maf. Fast forward like 2 days I got a new maf sensor and Edelbrock air filter. Disconnected the battery for about 30 mins after installing. It idled and drove okay for a bit and cel was ofd but after about 10 minutes of driving it went limp and killed the engine and the power steering and was throwing MAF codes again but not air temp codes. Anyone have an idea if it’s actually the sensor that’s bad or if it’s the 2.5l ecu being thrown off by the 2.0 engine? Or if there’s some other possibilities like wires, harnesses, or fuses? I’m super new to cars and I’m not sure where to start and I’m on a pretty tight budget so I’d appreciate some insight and advice before I start throwing money at the wrong issues. Thanks in advance.
