Hey Just picked up an 09 M8 153, first things firsts i put my 156 2.5 challenger on it. Now i've got about 80 miles on it ridin in Blue River (sic pow by the way!) Now im putin the slp pipe kit on it and i was looking for info on weather the boondocker box is best or the pure logic box. I had the boondocker on my 05 M7 and liked it but maybe ones better than the other?
