i have a 2003 530i M-Sport. what would be the best chip/software for my car?

you have three choices from what I know,

Shark Injector - less expensive - small gains but basically reliable and well known

Upsolute chip - middle price - advertised big gains - not a very well known company

Dinan - expensive - Proven gains - The chip you buy when money is no object

there may be more, can anyone else chime in?

*edit*
oops,
The Diana looks like it is only $299 - Upsolute is the most expensive

Is it true that the Dinan chip (or any other chip) will work best when you get the entire package.

I'm thinking abou the Dinan S Package (Chip, CAI and much more)

Thanks,
Dave

What about EAT? I remember reading good things about their stuff.

What is this "Diana" chip you speak of? I'm intrigued.
