Welcome fellow R3T Tx rider --- I also have D&D's since they first came out love them -- loud enough but not ridiculous... I had a dealer tune for awhile but when I change filter and a few other things I re-mapped it using the free tune editor and increase both my preformance and mpg at 70+.... would recommend you look at avons or commanders for tires the cement tears up the small 180 metz... and I am in houston and not on much here but answer my emails...
