adjustable FPR and WBO2?

#1

have you guys found an adjustable FPR "necessary"?

Is WBO2 monitoring helpful or unnecessary because these cars are so close to stock?

thanks,

It would only be useful in determining if your engine needs a tuneup.

Honestly, the cars are doing fine with stock fuel pressure and O2 sensors. My car has been very reliable so I’ll leave it alone.
