Boost problem !

[supson]

Hi all

I seem to have a boost problem, the story goes like this..... had a 3rd gen for 2 years now (stock 93), 6 months ago I had an engine rebuild. I have been running it in since, so no high revs and no high boost, until today ! Floored it in 4th at 2500 rpm, and the boost starts to build then the boost cuts in and out until the red line !

Any idea where I should be looking ?

Regards
Steve
