Back from the "X5 clinic"

[tomwac]

Result:
original values:
hp -> 202
Nm -> 525

now:
hp -> 280
Nm -> 675

All I can say is that I only did a 0-100km sprint and timed it/ before it was around 9.8 seconds (avarage), now I clocked it down on 7.9.
I'll scan and post the dyno output tonight. On the way back I was behind a 330Ci and when he floored it, I stayed right on his @ss. Couldn't pass him, but he couldn't drive away from me. I'll do some more timing and let you know.

What was done on the car to get this performance improvment?

Custom reprogramming of the motor management software.
It took them 7 hours, as it's not off the shelf. They program every car individually.

unfortunately for all the US guys...yes, a turbo diesel engine is much easier to tune than a pertrol engine. The same guy gets 260hp and 340Nm out of the X5 3.0i. And it costs 4000 euro, while tuning my diesel was 960 euro.

Mindblowing torque figure, serious stuff and supercar territory.
What kind of process did this involve?
Were you "permitted" to stay with your vehicle
while they performed their magic?

Well, I didn't understand the "magic" they were doing, but the car was on a dyno all the time (at least the first 1.5 hours until I got bored and drove back to work ) but they have a basis mapping that the owner of this tuningcompany wrote himself, and then they are doing adjustments for every car individually. So they measured the output, smoke etc and then back to the computer to make some adjustments. Uploaded the new software and back on the dyno...at 1 point they had 295hp and 720Nm, but the car was smoking too much so they had to find a compromise. Now, the car smokes a bit when floored or in kickdown, but very,very acceptable. He did say that my car had a few ponies short in original configuration but that's probably due to the backtuning the Belgian importer does on all X5's for the Belgian market. 211hp iso 218 due to taxation.
