Theres a whole bunch of things that can cause it, likely culprts are a tune that doesnt match the modifications or a faulty sensor.

I'd guess it's a vacuum leak or a failing sensor.

Thanks for the fast reply’s I had a look at the vacuum hoses and found one wasn’t hooked up to anything, does anyone know where this goes?

This is how the factory boost controller is set up:

So the circled port on your picture would go to a port on the plastic intake. The lower hose in your setup goes to a "T" on the turbo, between the 2 vacuum ports on it.
