I have the NM Module on mine set to high running 94 octane. Love it! But, I plan to remove it whenever I take it in to the dealer. It's just one plug and the velcro on the module sticks to the battery cover, so once removed there is no evidence it was ever there. The first thing they'll notice is the Cravenspeed intake anyway and since that's a pretty much benign mod, I'm not worried about that. I am having the JCW Pro Tuning Kit installed after the first of the year. I'm having my independent Mini Tech order and install it and the OTD price will be about 2K. He's also going to install my new headlight switch and enable my rear fogs.
