Oh I didnt realise that, I thought you would just see a higher boost pressure if the intake side was restrictive no? People run T34's etc without problems and my turbo isnt that big!

4000rpm it starts, I could try that but as you say it covering up rather than fixing.

Yeah I see what your saying Dazc
