A couple of things catch the eye.
Pressure exchange solenoid plumbed into itself on the inner wing, possible reason your CEL is on, will be reason your CEL is lit if the ECU is std
Boost solenoid not plumbed in
Phase 1.5 engine
What age is the car?
What ECU is in the footwell, could well be aftermarket if the exchange solenoid is plumbed into itself
re, Rolling Road, i would get the car tested with a wideband unit and det cans before putting it on the rollers to make sure the fuelling is safe enough
