Inliners International Forums General Discussion Hi Performance 4.2 VVT function

Does the VVT change or kick out based upon a pre determined rpm level or something else?

At full throttle starting at about 35mph and 2500rpm, in a lite 1500 pound chassis, when do you think the VVT would kick out?

Thanks, Steve

In the GM PCM its based on RPM and load (torque).

This is in a 4200# trailblazer.

In a light chassis it would be really noticable.
