I`m looking to take my car into a tuner, and the nearest one to me is (see title) in Maidenhead Berks.

I was wondering if anyone on here has used them before?
Does one of the people who works there comes on here?
Are they well priced? Do they carry out car check ups?

In the long term i`m looking to have mild work done to my car to see it near 200bhp, would they carry this work out?

thanks
