    Whipple 392

    So I've just got my car running with the whipple, runs decent enough with the whipple tune I recieved but lacks in certain areas. My main issues is it feel like a dog down low and part throttle also I have the light switch effect and goes from 2# to 7# instantly on hard acceleration and wot pulls. I believe both are related to the airflow tables but just wanted to ask if this is were I should start? Or could it be cam timing? Cant post tune now but will later. Car is all stock besides blower.

    Do some comparing. look at exh cam timing and throttle air flow. I and others have had the same thing happen with boost surge on light throttle up and light switch effect.
