How can you check if Turbo is spooling

Like the topic say, what are ways to check to see if the turbo is spooling and you're getting boost?

what rpm do you feel the turbo spool up? mostly likely though, you're just used to it. Took me a week to get used to my car. I guess i was all excited when i first got the car and worshipped its power, and now i'm taking its performance for granted

I can hear it start spooling at around 2900k but after like 3500 it boost doesnt increase it seems like it remains the same.

Do you have a boost gauge installed in your car?

Have you added anything to the engine?

You could also try an ECU reset to see if your original performance comes back. Disconnect the negative battery terminal, sit in the car and press the brake pedal and release a few times, then re-connect the negative battery cable. You may lose your radio presets and trip odometer reading (but not the main odometer).
