Boost Issue

[Mulv]

Hi,
Wondering if anyone can shed any light on this....
My new FD seems to have developed an issue.  Drives fine, idles fine and engine seems great....
up to about 4.5-5k RPM all seems fine boostwise, full boost and pulls great.
Soon as I go over that rpm I seem to loose all boost - engine still seems to be running fine though, if I back off then accelerate again, there is no boost for about 10-20sec, but after that all is back to normal if I stay below 5k.

Now I am going to try to change all the vacume hoses to see if that solves the issue, but I was wondering if anyone else has any ideas on this one??

Thanks

Its probably a failing boost solinoid for the secondary turbo, common issue on the FDs

ok I\'ll have a go at replacing that too, is that an easy job?  If so where would I be likley to source one from??

thanks
