How do you have it hooked up? how much psi does it go over?

from the compressor housing (or any good boost source) to the boost controller then from the boost controller to the wastgate. try removing the boost controller and just runnign your line straight to the wastegate, see if you are still spiking.

that'll work. I have mine t'd off going to the brake booster line.

but a shitty bc can do that...
Also, how old is the wastegate and it's spring?
It's hard to boost more than 2X the springs psi without spiking issues.
