    Car boosting strange

    Hi guys need some advice , car had been boosting weird , if input car into 4th gear and put foot down it starts to pull then when it gets to 3000rpm it will jump to 4000rpm and deliver boost weird , I have a video of this and will upload when I am on my pc later , after driving the car last night again it seemed like there is a boost leak now as it sounded like I had a dump valve and no boost in some gears ? Then other times it would boost ? Cheers for any input on this

    Check your Diverter Valve, they are known to cause issues when knackered. Check which revision you have. Rev D seems to be the popular one, but I went to Rev G as I was informed it is the better of the 2.
