The BMW powerbox does what it says: A bit more HP, and significant options to remap the throttle response. But after several months, I'm finding it's too aggressive (the horror!) for my daily driver, in heavy traffic.
So I'm trying to guage whether there is interest in it, before I take the time to disassemble the TCU to remove it.
The price new with shipping is close to $300. I'm looking to get $199 plus PP fees and shipping to the lower 48. 10% Discount for in person sale in the SF Bay Area. You can pay close to 50% more and get a new one, but since there are no moving parts, you can save $ and buy mine.
