Setting Wastegate Preload
In the videos below we will show you 3 different settings including zero, standard, and high preload. These adjustments can be made while the turbo is in the car and should not require removal for most applications.
Zero Preload is simple it's where the actuator arm will slide on and off the wastegate arm with very little effort. The preload setting would cause the wastegate be be blown open at lower than optimal boost pressure.
Standard Preload setting is what we recommend for the majority of applications and will allow the wastegate to remain shut at normal boost pressure around 25psi.
High Preload is what we recommend for people shooting for the stars (28PSI+), this allows the wastegate actuator to remain shut for those few extra ponies!
