2002 525i upgrade

[MTBL525i]

Hello all,
I bought a 2002 525i a couple of months ago and since there is a DINAN shop right across from my job I've been seriously considering some upgrades. The car is an automatic with the sport package and I'm wondering if its worth doing any upgrades or if there are any other alternatives out there - the only ones I'm fairly familiar with are DINAN and HARTGE. The car is in excellent condition and is the best thing I've ever driven - honeslty I don't need the upgrades but who doesn't want a little extra power/perfomance?

Just about anything Dinan sells so does Bavarian Auto, Bimmerparts, and many more for less. I am a Dinan fan and have many Dinan upgrades but they usually run higher! By the way, Welcome to the board!

Did you ever make the Dinan upgrades to the 525i? If so, what did you learn as I am about to take the leap as well.

Thanks Darren

I actually just started doing the upgrades in december, so far I've had the transmission software upgrade, stage 2 engine software and a cold air intake. I'll be adding a strut bar and exhaust in a couple of weeks. With the 3 additions though there is a noticeable difference in the accelaration and shifting and the car is even more fun to drive, my foot has got a little heavier post upgrades. I'm happy with the upgrades I have and will continue with Dinan but I should say that these upgrades are not cheap and the gains are modest for the expense you incur. I'm yet to get back on the dyno to see the new numbers but I'm sure the HP gains are overstated as with most tuners.

I work across the street from the Dinan shop and that was a factor in my decision to go that route, there are cheaper options out there though so I'd say just look at all options before you "jump"

Thanks.
I'm getting CAI, Throttle Body, and Stage 3 and Tranny software installed on Monday. I don't expect much but I think the badge is a cool conversation starter. I'm actually thinking about getting the engine software for my wife's 2000 323i without telling her (i wonder if she'd notice).

Let me know what Mr. Dyno says.

Take care
