First of all welcome to MRC :wave
Sounds like you have a split or an intercooler hose leak
If you have a stock intercooler look at the lower connecting pipe in front of the fan belts as these split and you get little or no boost at all, you need to take it off to check it properly
Hope this helps
Hi there! Welcome to the forum, as Clive said, it might just be a split hose or something - car isn\'t exactly brand new anymore, or it could be an issue with a boost solinoid as its a common problem on FDs, but usually if you can\'t get boost higher up the rev range, so checking for a boost/vac leak is a good place to start.
