I'm lost for words Smokey, look what you've done!!!!
Not only have you been very helpful to me on this forum, but take a look at the concourse work you have done to this vehicle!

I hope you are proud, you should be, its looks fantastic!

We still have our 2006 E53 3.0d Sport/Premium package X5
But i am going to have to sit down and read your build thread throughly, some great advise and hard work in there.
I love what you have done, congratulations mate, i know how long and hard you were looking for the right vehicle.
P.S. And i thought i had OCD

It's also made me realise, how much our X5 3.0d Sports/Premium came standard with.
So many things i just took for granted, but were missing on other 3.0d X5s'.

I'll be trying the ERG Delete, i am sure it will solve that horrible lag you can get when you hit the gas right at the wrong time for the motor and ECU, when they seem to be having an argument, instead of working together
And that Head Unit, what a job.
I looked up the UK company... So, they still use the Amp in the boot of car (Radio Module) to connect too?

Did you ever have any issues with the output transistors on the OEM Radio Module in the boot?
(IE: Speakers dropping out)

I'd be interested in getting the ECU remapping, but, we are pretty happy with power (Yes, more is always better)
But not sure i can spend the coin just to lean the car out Would be nice though.
