Which Mod first?
 

I've had my new car for just over a couple of weeks, UK spec X5 3.0i Sport.

I think it's fantastic, with only 2 real complaints

1. It's a bit slow and I need to overtake!

2. The exhausts look ok, but every time I see 4.8 tips I get a bit excited :wow:

The solution:-

1. ECU upgrade, taking power to 300 bhp & torque 244 lb/ft

2. Custom made stainless steel exhausts with polished 3 x 6 inch oval pipes.

My problem is I can't afford to do both at the same time, actually I probably could but my wife would either hang me by my balls or no sex for 6 months :o !

So please help me out people, what would you do first?

May I ask how you are gonna take your 3.0i to 300hp :confused: ? I'd like in on it.

upgrade.........
 

I would probably go for the engine upgrade 1st. I have an '02 3.0i and I just recently did the DINAN engine software and transmission software install and I am EXTREMELY happy with the result.........it now has that extra punch!
I also put the OEM chrome exhaust tips on mine and I like that look too.......
Let us know what you do 1st.........(engine, engine, engine)
300 hp would be awesome in that thing...........what do they do?

Its a UK company that visit your house, I'm sure you can find a US company to do the same
