Actually, I heard a lot of popping after installing an afe cold air intake on my ecoboost. Reading up, it seems its called turbo bark which apparently means the release of the extra unused air created by the turbos. I'm guessing with the higher volume cold air intake, the turbos produce more air than can be received or used by the engine. This is where I'm still playing around with different combinations of tunes and exhaust as well. Hopefully, I'll have enough time this weekend to install an afe cat back exhaust. Loving the extra power.Originally Posted by BFEB
