Odd engine braking question
So, sometimes when I pound it in 3rd or 4th and let it engine brake from 7k or so it feels weird. Like in the way it feels like it's not engine braking but then it will kick on and start engine braking. It's hard to explain. Basically it feels like I'm making no vacuum and then all of a sudden is does.
Thing is, I've logged my ECU and it is pulling normal vacuum according to the Haltech.
Any idea as to what it could be or am I just being paranoid and nothing is wrong?
It dosent' seem to act up in 2nd at all.

Yeah, letting it open, or it's hung up on something a little bit. There was a little valve thingy on NAs, but it slowed the plate down a very small amount before letting it close all the way. Basically to stop it from snapping shut completely.

Make sure your butterfly plate is not open perfectly parallel to the ground. I had a problem on my car where it was opening too far and for some reason, I guess the way air flows, it would not close immediately. I adjusted the stop just a touch and it's worked since.
