This might be a dumb question for an old bloke,.

How do I check my car is getting full throttle.

Skids

As above

Or turn key to on position but don't start the car. Take off the crossover etc in front of the throttle body and watch the butterfly as you push the pedal. It won't go a full 90° though I'm pretty sure. More like 85°? Also, it will shake in position, I'm told this is normal (by the guy above actually hahaha).

A vid of mine:

If you feel your car is sluggish try cleaning the throttle body and boost solenoid (REMEMBER TO RECONNECT THE HOSE OR IT OVER BOOSTS!)

data log it, that is the only way to see it is staying fully open at wot

Logging FTW. And since it's electronic, you can log a commanded throttle position but also the actual throttle position, if I remember correctly? IE foot to the floor doesn't mean full throttle is what the car will actually decide to do.

correct, torque management and the driver may disagree at times
