Hi all, I have been looking into getting my 2008 Cayenne Turbo remapped, but confused why there is such a difference in price range from the companies when checking online.

There are a few companies in Scotland Central belt, that can do for £150 and they claim an extra 72bhp and 66lb/ft.

Some companies, won't say their names, are charging up to £500/£600 for the remap or other companies sell things like 'Smartphone controlled ECU Re-Map' for £380.

Any advice is greatly appreciated..
