Lang 108

Bill,
I recently purchased a lang 108 and have used it twice. I have a mobile BBQ unit.
I am using the maverick that you sell and have found that the temp. on the grill grate is about 50 degree hotter than the therm. on the lang, is this normal or will it even out with more use?
Also do you know anything about cooking hot and fast for butts and ribs i.e. temps and times?
I had made a reverse flow smoker out of a 275 gal. fuel oil tank and it worked great as far as therm. temps on the lid and the like, but since using the maverick I am a little confused about which one I should follow, can you give me some guidance?
I am going to be open every day and am doing it by myself and need some advice.
