I know a lot of turbo guys have used the secondary o2 bung...
But has anyone used it to tune an all motor build accurately?
I ask because I have a header on my current build and the primary o2 is seized...Seized and rounded.
So, I either tune with the secondary bung or wait until I install a new header and tune.
OR tune on the second bung and tune again when I've replaced the header.
I know people have done it...I guess I'm asking those people what their experiences have been.
Thoughts?
