One tip for evading your police wanted level is don't travel in straight lines (try to outrun them on the highways). Head for an area that is heavily populated with buildings. Drive around and keep changing direction (turning left and right as often as you can). Head down alley ways and such. If you simply try to outrun the cops they will catch up with you no matter how far away from them you get.If the cops loose site of you but you are still within the cops radar zone then changing direction will loose them. If they loose site of you they will keep heading the same direction to try and catch up to you, so if your changed direction whilst out of site change direction. As soon as you get outside of the police radar zone on your GPS. Stop! This will prevent you from running into the cops again and restarting the chase. This method does require some driving experience so do this once you are comfortable with driving.

An easy method to do the deliveries for Jacob. You do not have to use the car he supplies to deliver the packages. So when you receive the job, get in a good car with good handling and head to his place. Reverse your car into the car space just in front of his vehicle. Get out of your car and enter his, the GPS target for the package drop will get added. Get out of his car and back into yours. Press the start button to pause the game and examine the map to find out where you need to go, and see if there is an easier way to go (straighter). Sometimes the GPS will have you turning left and right when you can simple take a straighter route which although longer is quicker to get to the target.

Another method I used. (requires the second island [Algonquin ] to not be open) Head to the elevated railway in Bohan (small North East island ) and climb the stairs to get to the platform. Once there jump down onto the tracks and walk to the middle. There is a central walkway between the two tracks. Follow this walkway along the tracks (anti clockwise) until you get to the rail tunnel that heads to Algonquin. Walk through the tunnel. When you reach about half way through the 6 star wanted level will trigger. Whilst in the tunnel I did not see any trains and the police will not come down there looking for you. If you decide to wonder the tunnels, don't stay near any of the underground stations for any long period as the police will enter the underground at them after a short time. I was able to spend over 30 minutes on the 6 star whilst wondering around the tunnels. Please note I did not see any trains whilst down there but keep in mind that you should keep left. If a train comes you'll be able to see it.
