For Sale GSX-S1000 Booster Plug. Improved the fuelling and snatch by a long way over stock. I was very happy with the value for money it provided. At the end I went a much pricier route; I bought the Woolich kit and remapped to solve completely. On the bike since Autumn last year. £120 new. As new and all parts in the box. About 30 minutes to fit and easily removable should you need to. £80 shipped UK.
