boost question after stage 2 upgrade
Hi all,
I just upgraded my car to a stage 2 tune (Chip + turbo inlet + cat back exhaust + dv) and wanted to ask if I should be concerned about the following, I was doing some runs and during one of them I had the boost peak briefly at ~28psi. Graph enclosed.

28 psi is a lot. Boost is higher when outside temps are higher ( correction for air density) Still though. Surprised you did not get an over boost code and limp mode. Mine is APR and peaks at about 24 psi on a warm day. Tails off as rpm rises above 5000 or so.
Check the hose from the Boost pipe to the N75 and from the N75 to the wastegate actuator. Leaks there can cause over boosting. |
