Yeah, that was about what I was guessing too. I decided to reinstall it yesterday after work. Can't say that it made a difference but the piece of mind is worth it. And it does take a while for the ECU to get its act together after a battery disconnect.
Also, the mounts are still rocking. It's like a car rejuvenation. But man is that tranny yelling at me now. You can hear what I think is the layshaft spinning, and the syncros spool and the gear engagement. It's totally nuts. As long as the vibes mute a little bit, like everyone seems to say they will, I'm sure I'll be very happy with the mounts for the foreseeable future.
Just being able to launch and feel your tires clawing at the pavement makes it so worth it.
