The day after, I was beating on it moderately hard. Lots of pulls, never really foot to the floor or anything but just putting torque down and having fun doing it.
Fast forward to yesterday, and it started to not pull nearly as hard. It feels like boost isn’t building as quickly, and almost falls on its face in higher RPM. The other day in 6th gear on the highway you could tap the gas and get thrown back in your seat still at highway speed.. doesn’t really feel that way anymore.
Does this sound like it could be a boost leak or something like that? This is my first car with a turbo so cut me slack.
I did some data logging with BM3 but not sure what to look for on the graph. I tried to figure it out a bit, all I saw was my boost target didn’t go over like 17.8 or something at one point. I figured tuned it would’ve been a little higher, no?
If anybody could check it and see if I have anything to worry about, I would be beyond appreciative.

Your log is useless.
You need to do a log from 2500rpm to at least 6500rpm. Wot. Traction control completely off and you wanna do it in 3rd or 4th gear.
Do that and repost.
