Ever been bothered by the fact that the Dukes has an extra that adds the blower with 750BHP text on the car, but made no performance difference whatsoever, having the same speed as one without it?

Unlike the 1st version, this was modified in 3DSMax with Openformats IO plugin, so the unecessary extras are actually removed instead of being hidden away. You can now use this as a gang car without issues (but first, you should wait until I release the Highway Reaper ped to go along with it, release date dunno).

I personally recommend adding it as a new car with it's own unique handling worthy of it's looks (included in the archive) while replacing the original Dukes with one that doesn't include the blower (such as JoeVK's Dukes Classic mod)
