that is an 8 valve and i didn,t think they had them in 2005. according to your chassis number RHZ its the right engine. get an 8v map into it and start from there.

It wont have a 16 valve ecu as it is an 8 valve from new going by the engine code.

Only way it could have a 16 valve ecu is if someone has fitted it and somehow got it to work but why bother 8 valve ecus are easy to find !!

If that means boost pressure then 28psi is too high and that's why boost is dropping off the ecu is stopping it
28psi is nearly 2 bar my fire breathing Subaru does not even make 2 bar on both turbos !!

Yea it's boost..

Just watching it in 3rd gear low rpm foot down it spikes at 36psi drops to 20psi and builds boost back up to 28psi

Afr on tick over is 16 on acceleration anywhere from. 70 - 92 which is stupid high I thought..

Guys coming back tomorrow who remapped it..

What psi should it be set to safely 25psi?

Afr is too high but could be the 16v map on there..

We will soon see
