Re: Thinking of the 523i
boot release can b retrofitted at pml for a small fee.....
i got my original m5 kit thru europe...plus installation...all in i paid 3.6k.
not sure if 523 can be tuned. rob can only do the m54 at this moment. 40hp (on paper) only achievable if u do ur ecu on top of exhaust system from headers out, air-intake, pulleys...
of cos u may go the supercharge route and drop in a snail....
