Was it fitted correctly? The dawes device STOPS spiking.
The Basic Boost Controller holds the signal from the wastegate until it reaches the level that you have set. Because of its rapid actuation, "spiking" (momentarily exceeding the boost limit) is almost completely eliminated. If you already have a boost gauge installed, you will notice that your "factory" boost level will sometimes overshoot the intended peak (or "spike") and then settle back to a sustained level. Our controller is much less susceptible to these boost spikes, allowing you to use the full boost level programmed into your ECU. By using our boost controller, you may set the sustained boost to the level that the factory control used to spike to.
A mate had one fitted to his Scooby turbut & said it was a lot smoother driving & holding boost than before it was fitted.
