Increasing the diameter of the tube from the turbo control valve to the wastegate actuator would not increase the need for more pressure to open the gate. It would however, take longer to fill the tube with pressurized air to build to the pressure needed to open the gate. IE, if you increase the diameter of the tube from say ~3/8" to ~1/2" with an inline bulb/balloon and it takes ~6psi to open the wastegate, then it would take more air (albeit a very small amount more) to fill up the tube and bulb to obtain the 6psi of pressure required to open the gate. Which would maybe give you faster spoolup, but not more boost pressure. Right???? That might be a very very cheap way to increase spoolup.
