might be worth checking for an exhaust blow berfore the turbo, up pipe gaskets can blow not that noisy but makes a diffrence to spool.

Shouldn't be slow spooling then - check for leaks then maybe try Harvey Smith for a matched up-pipe

when you refer to rpm what gear is that in.
A vf23 should have 1bar boost by around 3300rpm in 4th (ish). As mentioned above, could be a blow or a split up-pipe. Could the be PFC mapping i.e the boost duty is quite low and hence it's taking longer to reach target.
