Went to the Ring gain yesterday and experienced a loss of power halfway in the lap on a flat out bit... ST just wouldnt go above 110mph Suppose that's the overboost cutting out?
To be seen starting at 5:24 in the video: https://www.youtube.com/watch?v=s8eYIg74OdA

last time i was doing that type of speed in the st its never done that mine just kept pulling and pulling,in the vid seems like something was holding it back,is that what it felt like ?

Yep definately felt like something was holding it back

Did 120-130 earlier in the lap so no issue there, nor on my topspeed runs on the autobahn

if its a one off then i wouldnt worry to much about it but by that video i would say it was not the over boost,defo something else

Had it on the lap before as well, same spot

could it be the altitude you were at?

the Evo only boosted to 1.6-1.7bar while there instead of the 1.8bar its mapped to

Dunno, don't think it should drop 30mph in top speed though?

its the ecu thinking its not safe to accelerate so probably saved the engine

Completely off on both laps (ofcourse )

Increased intake temps preventing overboost?

Doubt that as it was 2 degrees outside

even if that was the case that vid imo has nothing to do with the over boost its like it was set on a limit of some sort,you didnt have the mykey active did ya
