P&G is still going to give you the very best results. However, driving normal (constant speed) will now net you better mileage. Once MetroMPG did all the stuff to his Firefly he stopped P&Ging cause the difference was so little and it wasn't worth the extra work to do P&G. I believe he only does it now for competition. So, you need to test what constant speed will give you vs P&G. If the difference is small enough, just start driving normal, and coasting with your engine off when you don't need any power (down hills, to red lights/stop signs, etc).
