Last night while driving hard I noticed something. In 4th gear under full boost my wastegate dumps were open and then they closed for less than a second and opened back up several times. Sounds like braap for 2 sec then exhaust note for less than a sec. then braap. I recorded my boost in graph mode on the profec E01 and it read 10lbs with a less than a sec downward spike and back to then horizontal 10lbs boost line. There is no hesitation or studdering, just weird with boost drop spikes. What would cause this?

 

Maybe the boost cut feature?

 

Thats what I was thinking since it's colder and there is a greater chance for higher boost.
