Then it's set for that boost on the bleed valve, even if it did have aftermarket chip ECU has no control over boost with those things, much better to use standard amal valve. If you plumbed this back in then it would run standard boost. That power at standard boost sounds about right if you consider the age of the engine and wear.

Standard actuator is not crap and at your state of tune you don't need an uprated one.

However if you are running standard car you should not be running that boost you will melt it, what was done when the car was setup?
