to N51/52/53 engine owners. i have a BMS power box for sale.
retails for 280 in the US, im after 150. below is the product information i lifted from europeanautosource.com. personally, i found the biggest benefit was the improved throttle response; on its strongest setting i felt like i could control the power better and that it came faster than when i had it reset to the stock map. overall, it gave me thrills. im selling now because i took it off and ive been ceebs to reinstall it.
sydney, pick up preferred but will ship at buyers expense.
