Turbosmart recommends the ideal setup for achieving your target boost pressure is to use the wastegate actuator in
conjunction with a Turbosmart e-Boost controller.
IMPORTANT NOTES ON SETTING THE WASTEGATE ACTUATOR SPRING PRESSURE
A stiffer spring should only be used when necessary. The wastegate actuator allows for different combinations of spring pressures. All
springs that are adaptable with the wastegate actuator are shown in the table below. The tuner can use combinations of up to 3 springs
to achieve the following base boost pressures. To aid in the identification of these springs they are supplied colour coded. If this colour
coding is not clear please use the dimensions in the following table to identify the spring. Please see the following detailed instructions
on setting your wastegate actuator spring pressure. The springs chosen should be rated to the lowest boost level desired.

Changing the springs
WARNING! Fitting a heavier wastegate actuator spring may cause a higher than expected increase in boost pressure.
Turbosmart recommends adjusting your boost controller back to its minimum setting and measuring the new minimum boost pressure
achieved by the new spring, before increasing your boost pressure again
