Try taking the lid off the smoker box and opening the side vents as far as they let you, then adjust the gas to you reach your desired temp. I also like to use a mix of chips and chunks, the chips will catch quicker and then get the chunks going, and I don't soak mine either. Good Luck and let us know
BTW... there are also some mods you can do for the smoker box... check out the propane section
