gday, a mate has a blue v6 vn "dealer pack" or woteva they call the cars that came with an HDT improved ecu, fe2 suspension, lsd, and wot appear to be colour coded vn gts rims. its not an HDT numbered car tho. does anyone know if these cars had a different cam profile or any other internal change as part of the HDT improvement?, or is it just a different tune? cheers.
Doubt any of the dealer pack cars had different cams or internal bits. All mods were more like bolt on and memcal recalibration. Exhaust and air intake were the most common. The SV3800 had a bit of a tune in it - but even that has been improved on now days.
