Can I adjust my wastegate ???

[Vandermax]

I know I can buy a turbo master, but I was wondering if anyone has adjusted the wastegate with a wire or something?? What will it do?? allow more boost??? is is a noticable gain????

What year truck? Fill out a signature please.

Vac system you can rig up boost fooler for ECM. A fooled ECM thinks boost is low so it commands wastegate solenoid for more duty cycle which increases boost.

Older spring waste gate I don't know.

Wiring shut is bad idea for long term. The wastegate prevents too high of spikes of boost by bleeding off excess turbine gases.
