Nice looking SST, real clean.
You seem to be confused about what GVWR means. My Indy has a GVWR of 6400lbs which should be the same as your SST. GVWR (gross vehicle weight rating) is the total permissable weight of the vehicle, this is including driver, passenger & load. It is not the curb weight of your truck. Your truck weighs 4500lbs and has a payload capicity of 1900lbs.
FYI, that JET chip is not helping your performance. Dyno & track testing have proved they cost power, not increase.
Be sure to drop into the genII forum if you want to learn more about your truck as well as what else works or doesnt as far as performance
