bm3 Stage 2

I just flashed bootmod3 stage 2 93 tune.

I was wondering if there are any consequences if i do not have a high flow downpipe. I understand i will not be getting the most out of the tune if i don’t upgrade to a better downpipe (mines stock).

I am more or less wondering if I will cause any damage to the turbo or exhaust if i’m running this tune without an upgrade one.

I drove around for probably about 40 minutes after flashing. Let it warm up and the car feels a lot different.

Faster shifting, noticeably more pull, and sounds a little meaner.

Please let me know what you guys think on this. I plan on upgrading the downpipe at some point but want to know if its urgent and i should go back to my stock tune or stage 1.
