I used the Burger module. It never caused any issues, but drivability wasn't perfect. You could feel the extra power, but when going up a steep hill or anywhere in mid-throttle on a warm day it would stutter a bit. If there was something that gave true factory drivability plus the extra power then I'd be interested. The piggyback units just aren't up to snuff IMO.
