I installed these along with wc fab emissions intact down pipe. These seem to wake up the turbo along with the down pipe. I am not tuned yet just a derringer. Most of my dead peddle seems to be gone now. I am very happy with the upgrade even with the amount of hours I put in changing them out in my driveway. Cant wait to see what happens when I get ecm and tcm tuning.
