Hi i'm new to this forum so i apologise if this has been brought up before
i'm thinking about buying a performance chip for my 530d e39 model, has anyone brought one for their car, if so which one did you buy and what was the difference in power and mpg, i have been looking on ebay and found one that i like, it's called Drakebox2 cost £80, the seller has had over 3200 postive feedback and only 5 negative in the last 12 months, it comes from Italy gives you 33% more bhp and upto 20% better mpg.
I appreciate any help on this subject
