Ok this is simple, go through the route as normal, and run down the two miners you first see, plant the bomb and head off again. Then kill other guy with any weapon of your choice. This happens when you place 2nd bomb down. I used a shotgun but personally use a mingun. Then you got the forrelli gang members right,Simple get out of your car just at the start of that tunnel entrance and Bazooka them. Then drive van out of the tunnel by ramming it through the gate shown on the map
