I went to the track yesterday and got an error code on my Type R. I didn’t have any issues in the morning but i felt the low power output. However, in the afternoon the problem started showing up.

We were able to clear the code, but when I went back out for another run, it came back on the third lap. We cleared it again afterward.

Have you ever seen this issue before? The code is P0299 – Turbocharger Underboost. Just wondering what you think might be causing it.

Sounds like you have a leak. Hose clamp or bolts have worked loose is my first assumption. Go over everything and find it.
