Right, pulled off the Manual Boost Controller and it seems to have got a lot more bottom end, but it still won't boost past 5 psi. I think the boost controller might have been the wrong way round causing a boost leak, but that doesn't explain why it has more pickup with it off, since surely the boost leak would be better in that case and therefore it would be slower? Before it was completely flat now it has some punch but still only up to about 4 psi.
