To be fair to Dinan, this thing wasn't installed properly. The CEL was due to turbulence and that was because they took out the snorkels which left large holes in the bottom of the air box. It turns out that the Dinan solution requires a closed airbox, the extra air comes from the new scoops in the cold air intake. My car is being fixed with a new bottom on each air box that is solid. Now the DTronics should perform optimally. I am fairly certain it wasn't working as well as it should because the airflow data was bad.

P.S. I am not having to pay for the different plates on the bottom or the labor, Dinan is covering that.
