Hi, I'm new in this forum but I know alot of things about bmw 530i 2004 and 2005...
I have bmw 530i 2004, it was 230 hp... but now it is 290 hp (+60hp)!!!
because my car has:
1) surge performance chip. and
2) 1 psi supercharger kit.. (the best intake system for bmw 530i).
my car is doing 0-60 mile in 5.8 seconds!!!
and quarter mile in 14.5 seconds..
I want more power in my car... so, i will buy BORLA exhaust system and an ECU programmer..
ANY COMMENTS OR SUGGESTION!!!!!!!!!!!!!
