I'm in the same boat. There are a lot of claims but also a lot of confusion - at least for me over which version of the N63 these tuners are using.

And it appears none of the customers are verifying the gains on a dyno. It just 'feels faster'.

I'd like to see a customer with a 400HP N63 with baseline and tuned charts.

I'm also a huge fan of the JB platform and ran it on my 335i for 4 years without a hiccup, I wish Terry would move to a Stage 2 module. I need more than 25whp.
