Hey all was hoping anyone could give me their opinion on this dump valve
http://www.autostyle.co.za/product/17699/MaxPowerLargePerformanceDumpvalve/
i currently have this in my car and before someone comments it was on the car when i bought it...
Is it worth while or must i change it??
Secondly it has an adjustable screw at the back what would that adjust the dump niose or the pressure??
Thanks 🙂
