How to find out if car has a tune?

I purchased my car november and have been modding quickly. But researching a little(planned to buy evolve tune) i heard smg downshift "blip".

My real question, ive read everywhere that smg doesnt "blip" the throttle when downshifting "without pressing the gas"

But when i downshift (anytime above 2500 rpms without throttle) my car blips the throttle. Every time.

So how do i go upon finding out if i have a tune or not?

Why wouldn't your car blip the throttle to downshift?

I was under the impression that it only blips the throttle while you are holding the gas peddle. Mine does it even with my foot completely off the gas.

I might not be fully understanding what you mean, and forgive me if I'm saying it like you are stupid, but your transmission has to blip the throttle on a downshift to keep you moving at the same speed. Even if the transmission didn't do this action, your road speed would do it for you, like with a manual.

I'm surprised it was registered. Must've had the dme sent to AA themselves for the tune.
