The level of ferocity with which the tach now climbs just means I feel like I have to shift a lot, which isn't a bad thing it just isn't something I'm used to never having owned an 8 speed before.

Executive summary: get one. If you dont like it, sell it for a $20 loss. Seriously, 15 minutes start to finish. You don't even have to remove the cowling like the instructions for the 3 series show, just 4 plug interceptions and go like hell.
Where did you place the jb3 head unit? Got pics or instructions?

Had the n55 stage 1 burger tune installed about a month ago. The extra torque is nice especially with the manual transmission. Got it up to 130 mph in no time. Just worried if i have to take it in for a service what to do.

Tomorrow I will be raising the boost by 2-3 PSI which should net a few more horsepower. I'll report back.

FYI, looking at the install guides seems quite daunting but literally, with almost no tools at all the unit was in and running in 20 minutes start to finish.
What boost level are you seeing the best results?
