RE: NOS on 06 f4i
Just curious what other f4i owners thought of NOS. I have it on mine and have for about a year now. It is a blast to mess around with. I have not had any engine problems up to this point. I ti s dry kit and I have an MPS FI controller which adjusts the fuel mixture to safely use the NOS. I have not put it on the track yet though to check times but hopefully will soon. I still have factory exhaust. Any suggestions for a good exhaust?
