Both, Stage 1 JB hybrid in my daily and i purchased GC DBB last week for the project car. Nothing but good results so far which made me buy the upgraded kit. i have the daily on 20-21psi atm, ive heard good and bad about Pure turbos but its all up to the customer/project i believe.

Why would you want/need a third O2 sensor?

Personal Preference* , But to explain without arguing or going back and forth because this is my opinion. To monitor EGTs for example, You can get a/f ratio gauge by using them. wideband is much more precise, descriptive, & useful for tuning performance applications than its narrowband counterparts. Narrowband is only good for seeing if you are running lean. Depending on the tune, the AFR reading could be a "corrected" reading in datalogs. As much as the OEM sensors are wideband you can simply hook up an external gauge to them to see. A Wideband/gauge would allow you to set a gauge in the car to offer real time, REAL AFR, with no bias/correction factors, or need for a laptop to view. Widebands are used more by tuners for proper A/F ratio adjustment and so forth. Unless you plan on changing parameters, this would not be a necessity for you personally. But at the end of the day your car is your car and what you do to it is your preference
