P0243 overboost

The Ram keeps storing an overboost code, P0243, I think. It’s not throwing the check engine light.

I’m not even sure if it has a stock turbo. If it doesn’t, that explains the overboost code, since there’s probably not a boost fooler on it.

If not, it could be a bad MAP sensor ($107 from AutoZone). Or it could be something wrong with the wastegate.

But, it’s running great.
