I got them from design911.co.uk got them within a week of ordering.
Iv heard that the mill wont be affected due to the location of the o2 bungs however the mill will be mapped out on the stage 2 anyway.
I don't understand how come Mrc can get high 400's & all the other tuners revo,apr etc etc can only get mid 400's
Have anyone dynoed there Mrc cars at other dynos to see what you getting
Pooping on the party a bit- sorry guys: the spec you describe sounds like everything you need- the auto box is fabulous for driving too, I do still always recommend a manual audi, fast audi autos have never been kind to me. Regards to buying there are all kinds of specs out there so just hold on until the right one comes up, it'll be worth, I wanted a spec that was a bit unusual but I found a manual car that someone had literally ticked all the boxes after only a month. I'm not sure about the b and o system being worth it though because the old Bose I had had more power though the b and o is clearer (personal preference). Try and buy a standard one since the MRC mods are good value and then when you do want to get your mods done try get someone else to get it done with you (might do a deal). As for the power mrc claims are not inflated and boy these cars can move.
All the best and off course if I see something I'll share it.
