Update
So went yesterday evening to pick her up from MRC, missed her being on the dyno

but spoke to Doug and he showed me the carbon build up pictures on her. And it was bad really bad Doug if you could post the pictures that would be great!
Anyway after settling the bill I could not remove the smile of my face jumping with joy into her and starting her up.
The drive well Doug said you will notice a difference as I gained almost 70ps with the work done. So I drove her warmed her up and onto the M3 and WoW WoW WoW I was thrown back into the bucket seats!!!! I can't explain the joy I had on the M3 there were parts totally empty and I just floored it and I was in total heaven. She felt so comfortable even at high speeds it felt like even so I started to become nervous with the speed (police and cameras) she was wanting more pulling and pulling.
I did take a de-tour and the drive from MRC to my house normally takes 1hr and a half, I arrived home three hours later lol.
I am totally happy she looks amazing the front arches are now totally filled with the wheels and she looks evil from the front.
I even had a little race ok I admit totally unfair race but for some reason the guy in a vauxhall insigma wanted to race me I could not understand it maybe he missed the RS4 badge lol. When I left him for dust we met again at the traffic lights I looked over and just shook my head with a smile and he just smiled apoloetic.
MRC thank you for the work you guys have done I know as Doug said if I want more I need to get down pipes but the wife would kill me if this car gets any louder. I might just buy her a golf that she can drive.
Anyway I can only recommend getting inlets cleaned!!!!!!!!!
Thanks MRC
