Great review. I'm about to go your route. I got the same setup as you minus the BMW Performance Intake. Currently I'm using the AFE intake but the lag in going from 2nd to third that you get sometimes is pissing me off. I'm about to purchase the performace intake. How much did you pay for it? Did you get it from Tischner?
