Boost controller Or Spring

Re:Boost controller Or Spring
Springs do spool faster, its proven, we have tested a DSM wastegate actuator vs spring, and had about a 1000rpm sooner spool time. But springs can be a bitch to adjust, and will vary under types of loads. I only recommend the spring job unless you dont want to boost as high as your wastegate is set, or your wastegate is having clearence issues with your engine/cross member etc.
