Hey just wondering what kind of boost controller i can run on a sigma turbo?
Can any of the turbosmart ones be used, ora digital boost controller, ie; APEXi one???
I had an actuator type that wasnt really suited to adjust boost at around 10-20psi. i think it wa suited for much larger psi applications as the adjustment on the controller was way too touchy and it was either on stock wastegate boost or pretty much unlimited boost!!!
