No boost controller, I have a 3 port solenoid and have it all wired up. Not much time was spent on boost control due to the wastegate giving me the desired level of boost during mapping, I now want to run lower wastegate pressure and add boost control. Using the additional injector map should allow me to adjust duty cycle by RPM, obviously this is much more desirable than using the wastegate solely, or running a boost controller. I just don't want to mess up what's already there! I might pop in and see Will @ RDT who mapped it to ask for some advice. Just to be clear, I'm not looking to increase boost levels, I want to run the same, but have better control over it. Bleeding boost away from the wastegate should increase response, which is my aim here.
