My friend did it in Northallerton at his garage and got his mate to come do the remap was about £400 all in. And it’s not a bodge job either. You’d never know. I’ve just sold the car and I never had a problem where when I had adblue etc I was always coming into problems. And if you do what I said to the exhaust it be a different car. Leaving the exhaust silencers leaves too much back pressure when mapped. (Trust me I tried every way haha) I have a video of it just revving you also get the odd “choo” off throttle. A panel filter also is no good I got better performance from a ram air cone filter and used the original air box and induction.
