I got a go fast bits boost controller, set at 13psi, at full acceleration it goes up to 13psi but the falls and rises back to 13psi rapidly, I can feel the acceleration jumping and falling back accordingly, Spikestop is off on the boost controller, and when I turn off the controller and run wastegate 10psi it doesn't jump around at all, what could cause this? On a cold night it tends to be better behaved.

TVSV disconnected and lines are blocks off.

Explain to me, I have stock internal wastegate, and set the boost by increasing duty cycle slowly until I reach 13psi.

Should have a way to input the stock wastegate spring pressure, ive found that mine on the 3rd gen is around 6.5lbs pressure. then that feeds off the duty cycle
