Revo For B6 A4 1.8T

[silversurfer]

Hi,

I've heard good and bad thinks about remapping engines.. However there is a garage not far from my work that do the REVO remap's

What sort of price do people pay for this.? (My Audi is a 54 A4 1.8T S-line)

Do I need to upgarde my turbo inlet pipe, dump valve or air filter.?

Thanks

Neil
