I am new member and want to get expert advise on re-maping factory computer setting to imporve performance (acceleration and top speed). I am looking at Bavarian Autosport software upgrade for my 328Ci - 2000. Question, is it worth the $300? Will I notice a difference? I installed an aFe cold-air intake, and a REMUS exhaust and got a little more power (I want to belive that afetr soending $1,000).
