No
I get zero spike on my blitz dsbc-r
I have the unit sitting under the airbox, and feeds running directly to the wastegate actuators. There is probably no more than half a metre of hose going to the furthest actuator. Boost line comes off one of the hoses from the carbon canister sitting near the airbox. So really, if you reduce your hose lengths, you should reduce the amount of spiking.
Good luck
