Start with a boost solenoid and check for leaks on intercooler/boost hoses

If the car is standard, it should only boost to about half way.

Never had any issues at all with boost in over 9 years over 2 cars.

When I got mine it had a little flutter/miss at low rpm as you built the boost up slowly. Full throttle it would put hard and boost off the gauge but mine has been re mapped. I gave mine a service and new plugs and boost solenoid and it sorted my issue
