Sounds like you're sorting things fast pal. You might try cleaning your TB when you fit the k&n, this could be another reason for power loss. Give us a shout if u need a hand with the fitting of it or ur head unit. Also have u made a decision about friday? If ur cars still in garage, def come to the next one and get to meet us all, we're a good bunch and you'll have fun
