i got a cel the other night. it came in as p0244 which in the cobb ap booklet says it's a turbo wastegate selenoid "a" range/performance. the cel went away when i got in the car this morning. does this mean that i boosted to hard? i'm running stg2 with catless perrin dp. should i get a boost controller? what can i do to stop that from happening? should i be worried?
