Hi !

I will be getting the above combination when I do my performance upgrades on my 7. Thing is that there is no tuner around here with wideband O2. Now I'd need to know if taking the car to the tuner that only had dyno is even making any sense ? Can the tuner tune the car better then me with the PFC & datalogit ? Is WB O2 esential for tuning the 7 ? How hard is it to do it yourself ? (I think that getting J&S knock sensor would keep me on the safe side, but then again it's quite expensive).

 

Nobody knows this ? C'mon

 

Go the the PFC specific forum and check it out. There is more on this matter than you can shake a laptop at.
