Default I just went apr stg3 a few weeks ago from homebrew....

so MBC removed and the N75 plumbed back in. On my first WOT run I saw my gauge peg 25psi (like your video). Told my mechanic (in the passenger seat) to order a new N75 (based on something I'd read from Hal), and have been using throttle to modulate boost since. If you get the car into boost and hesitate around 2-10 psi, just for a half second, then floor it you won't get the spike.

I find this a bit counter intuitive since, I think, n75 cycling is supposed to increase boost.

your car has been like this for 10k miles? interesting...

It doesn't do it all the time. It is mainly in higher gears at 4500 rpm or so while jumpin on it.
