Got my tune from BBP so I neglected my domestic duties to load the tune and drive this girl.

Yes, once the trans learned its shifting again it is noticeably quicker. It runs out so much better than before. No more losing acceleration at each shift. She just runs smoother and with more power.

Did you try those O2 sensors out?
I just got mine today, denso marked
Seems ok there, but the pn on the box looks weird.
And the sensors don't have the expected little plastic protective cap.
If i were to guess, these are fakes.
