Caldina GTT Boost

[Technohedge]

Ive noticed when driving the turbo kicks in as one would expect around 2000 rpm, boosts nicely but at 3000 it feels like im back running no pressure? About to install a boost gauge to confirm this and check what levels its actually boosting too, but Im sure it feels like its not pulling as much past 3000

Any ideas of what to check for whilst Im putting in the gauge? The car is all stock, no aftermarket stuff fitted as far as Im aware

cheers

loose intercooler piping?

Or split piping on the boost side and which only opens up when there's enough boost....
