Have received my crd-t+ box from dtuk, now to go and fit it 
All fitted, I have set the box to program 3 +1. Is it normal for the lights to flash or should they be permanently on? P3 is flashing green and +1 is flashing red.
Not taken the car out yet for a test run

Hope this helped but one of the guys who have one will be able to tell you more
I missed that post, thanks. Mine is all good then.
Ok have taken the car for a 12 mile test run, with the setting at P3+2 and can honestly say what a difference the box has made!
Started in Eco mode and instantly noticed there was very little lag and so responsive. I really didn't like Eco mode before as you needed to plant your foot to get it to go........not anymore! It's so much better.
Then onto Normal mode, again so responsive. The pick up due to the extra torque is very noticeable
Sport mode, just when I thought it couldn't pull any harder, it did.
Although this was a short test drive, to me it has made a huge difference.
I'm impressed

and will only be taking the box off when it goes for a service etc.
