Default Normal boost? <Video included>

Im hitting about 20 psi when i go full throttle and the boost pretty much starts going back down to 10 from there, if you watch the video i hit 20 psi, and when i shift again i hit 20 again and the 2nd time it loses boost pretty quick, happens every time. Is this normal or some sort of boost leak? Normally if i go up to 5000-6000 rpm itll be down to 10psi. And yes my DV is upgraded to the 710n.

Yep, looks normal enough to me.

Boost really starts to drop off past 5k rpm on the K03. No real point shifting later than 5500.

Couldn't hurt to check for leaks but that seems pretty normal to me. What tune are you running?

I have a ko3s if that makes a big difference, but its just weird how it spikes 20 and literally jumps down to 15 then slowly starts losing boost after 15. And i have this tune UPsolute.com The Chiptuning Company

its just odd im reading peoples posts and their diffrent stage 1 tunes hold 17 psi.

All the tunes behave a little differently, it's all in how they are programmed.

I never hit 20psi with my tune. I peak at 18 and hold around 15-16 until it starts to taper off.
