I hope it's not an SLR chip, I had a similar one and it fried my sensor, made the car slower and dropped fuel economy. IDK if I would trust it but if you wanna try it I'll see what I can find.

I am fairly sure that Model year 2000+ Subaru Legacy cars abandoned the Whole Mass Air Flow sensor (MAF) technology and instead started using Manifold Absolute Pressure (MAP). I could be mistaken on this though.

I am not familiar with UK Subaru cars. My guess is that these car were built in Japan and closely follow JDM car technology. Based on what I know of US MAF implementation the MAF sensor would be installed in the air intake between the air filter and the black plastic intake lair intake pipe that is roughly 3-4 inches in diameter. I am not at all sure if UK cars utilize MAP or MAF sensor technology.

iat is in the intake beside the coil map right strut tower
