problem under load
 

we are having porblems with a legacy twin turbo auto...

it is cutting out intermittantly when at full chat or under load.

The coil packs have been checked and replaced with known good ones so this is not the prob, anyone got any ideas what it could be?

Also are the ECU codes the same as for the impreza?

check spark plugs? sounds like over boost?

perhaps wastegate Solenoid?
