Just picked up my SMARTY yesterday from Olee and man what a world of difference. I fell in love with my truck all over again. The difference that programmer made in my truck is absolutely phenominal - can't even begin to describe it. Who would have ever thought the VP44 could fuel like a P7100 but the Smarty does it. We'll be doing some track and dyno testing this week. Drag box and smarty are an awesome combo.
