Thanks John. I have a stupid question...how does one control the boost in a turbo? I have a Cayenne Turbo and it is either off or really on!! Typical turbo lag followed by thrust. Of course if you keep the RPMs low, you can reduce the boost but this is not really that effective. I remember DBK talking about the TT producing controllable power as compared to a sc like the Whipple. Excuse my ignorance on this subject.:wink Just want more clarification regarding the "boost controller".
