nope still no good - did as you advised and it's still not right.

It'll pull like a train through 1st and 2nd all the way to the redline - then in third it gets to 5000rpm and starts to cough and tries to suck more air but can't

In 4th it's the same but for much lower in the rev range????

I'm running it with a decat pipe and no dump valve at the moment - I've also got the stainless turbo boost hoses. Can't see why this would stop it working tho.

Can anyone help???? I'll try just about anything.
