I went to the drag strip last weekend, car ran great in the 1/8 mile. But it was a very hot day, and my IATs were skyrocketing waiting in line, around 160+.
It seemed like after every race, the car would get slower and slower until i had to stop to see whats was going on, also as i was waiting in line, i got a SES for trim control (running too rich) i cleared it, and it hasn't came back. I drove home, and it felt like I had a terrible boost leak. I hooked up MHD and checked my boost level, it was around 15 at peak. I normally get to 21+

What was strange was the more i drove the car, the higher my peak boost got, and the better the car felt.

When I did my log, i was hitting 18s, but it still felt very off.

As more time goes by, i'm now hitting 19s, but something isn't running right.

Here is a data log when the car felt great

There seems to be a lack of power, but its not enough to throw a code.

I'm wanting to get new turbos (hexon or VTT) but want to make sure everything is running perfect before i throw more power at it.

Some ideas of what it could be:
small boost leak somewhere. (my boost is only effected by ~2psi)
vaccum line leak?
waste gate?
turbos going out?

I'm pretty stumped about what to try since the car isn't throwing any codes.
