Choppy cold start post catless DP
Since installing catless DPs I've noticed the cold start being a lot more choppy than normal which I didn't notice on other builds. Other than that the car runs smooth but wasn't too sure if this choppy idle was the norm? I don't mind it at all as it's quite raw and aggressive

Sounds pretty normal I think. Did you flash with MHD or anything to reset adaptations?
