P0234

[G-630626]

Same thing happened to my 2021 Stinger this morning. I accelerated out of a stop light, I had loss of power then the check engine light came on. Same code as above, P0234 (Engine Overboost Condition). The temp was around 20 degrees F this morning when it happened.

The light is still on, I may call the dealer to have them take a look.

Repaired?

Nothing to repair.

Going back in my brain, my Stinger was overboosting because I had (at the time) Ark secondary downpipes, catback exhaust, plus less restrictive intake w/ Velossa Tech big mouth ram air horns; all while driving hard on a very cold morning, when the engine wasn't 100% at temp.

I've learned shortly after that and drive her easy (especially on cold mornings) until she's fully warmed up. Haven't had an overboost issue since.

I also don't have my Ark secondaries anymore, which can also help cause the issue.
