I had to compress the PDF because it was too large. I'll find another way to attach it.
Here is the link to the discussion (didn't see this when I posted earlier)

Old thread,
i know, but didnt know where else to post. I got this TSB done and the car rides a lot smoother, but it feels as if it lost some of its pep at the same time. Is it just me imagination or has anyone else felt this

I just got back from the Infiniti dealer a few minutes ago. Had this done this morning. The car shifts ALOT smoother. And I haven't lost any "pep". I think what you were feeling was the jerkiness of the shifting before. If anything, getting up to speed is actually faster.
Eh wont work. Had this done to my wifes sedan a month and a half ago
And it startwd shifting all messed up again a week or so later. I was hoping
When we did this the shuttering would go away but it only lasted a week.

I noticed this as well after the update. Its also noticeably quieter. Has any one who dyno'd it before gone back and noticed any lost horse power?
