Get a specific map from a reputable e-tuner or pro-tune by a reputable local tuner. Good luck, I'm sure you will be satisfied with the results.......and only a short matter of time before you are planning your next mods.
Not sure which cbe you purchased. But in regard to the Borla, it ships with the 2.5" adapter that will mate to the OEM dp or one of the OEM-like aftermarkets ones (i.e. Cobb). The reason some of us mentioned the 3" adapter is due to having to buy that separately (use it in place of the 2.5" adapter) when you are using a dp with the 3" outlet flange (i.e. Invidia).
