All I can say is BLIMEY!

It makes a massive difference - general acceleration is better - it is frighteningly fast now.

In gears 2 and 3 it is an absolute rocket - overtaking was easy before, but it just launches past other cars now.

It has also made the car more smooth to drive - first gear seems more progressive - its easier to feed the power through.

I dont know exectly what has been reprogrammed, but it seems to hold the gears a bit more in D. I havent tried sport mode yet - never used it much anyway, prefering to change manually if I want to get a move on. I have only done about 25 miles since the mod, and I was pootling as I had my family in the car most of the time, but it really has made the car an animal.

I think it will really go through rear tyres now - the traction light was keen to come on a lot sooner than before and pulling away from junctions briskly also makes the rears scrabble for grip.

All in all, I would thoroughly recommend it.

My bro had his X5 D Sport done at the same time and he said its now a different car, although it has shown up some weaknesses in the suspension when it comes to yawing (sp?) under heavy acceleration.

I can fully believe the 5 seconds 0-62, and 13 seconds to 100 feels like an under estimation - my Lotus Elise 111S didnt feel any quicker.

A man with a laptop comes and whips your engine management CPU out and plus it in to his comp and twiddles his keyboard....voila!

It is guaranteed undetectable and can be put back if you wish (why you would, I dont know).

They dont mess with fuelling so you get slightly better consumption and NO smoke.

Basically in a few months, BMW will bring out an uprated 535D sport (as they have with the 530D), and all they will have done is tinker with the engine management - same as these guys have done.

I am not one for modding at all - never had ANYTHING done before on any car, but the press write-ups were too good to pass up. I can also not afford an M5, and this is the next best thing.

Ride free, oil burning dudes

Chris, where did you get 5 and 13 seconds from? Isn't the best magazine time to 60 5.5 and I've managed 0-99.something in 13.8, but not 13....
