i don't know to whether decide if to get the BMS power box or the active autowerke performance chip software the BMS cost around $279 where as the active autowerke cost about $500 i don't know which to pick cause i heard about active autowerke product they are good but never heard really about BMS. cause for $500 i just get a 15 hp increase and the other i get 10, so i was thinking for $500 just 5 hp ill rather get the BMS and take my chances.so what do guys think active autowerke or BMS.

I would be prepared to get hit by the many suggestions to do a search first, especially in the NA Engine section as I'm pretty sure this question has been asked many times. Ex. http://www.e90post.com/forums/showth...ht=PowerBox+AA.
