Hey Guys
Hope you all well im pritty new to blogging or what ever they call it, Im from south africa and drive a Vw Polo 9n3 tdi asz. I have fitted a GTB2260vklr to the vehicle car has +100% injector, fmic,76mm straight pipe, 76mm intake. Im getting very bad serge at about 1.6bar +- 2800rpm until 1.8bar then its clean. I want to port the intake of the turbo to try fix the serge does anyone know what housing i can use besides the stock housing or if you had the same issue what did you do to solve it im going to try map it out and request boost a bit later.
Thanks guys
