Ok I had a little time on my side this morning. I swapped out my BDJ twin tube intake with my 100% discounted CODE3 intake ( Thanks Brandon ). It took all of 10 minutes to swap.
Maybe the ECU needs a bit to reset but the BDJ seems a little stronger off the bottom end. I still have the stock AMG filters as I just bought it with 11k miles on it. Maybe some sun dried K&N filters will help.
My BDJ has two K&N filters on the end instead of the Greddy style mushroom filters. I know they dynoed the BDJ around 26hp. The only drawback to the K&Ns is my car sounds like it's wearing head gear. Nice whistle.
The CODE3 pulley with the BDJ intake was very stong. There was no lag to the boost onset.
I'll cruise around in the 60 degree temps in the morning to see if the new intake picks up a little.

A Tune is next to come along with an exhaust.
