also a newbie here. i run the hypertech pp3 on my 05, as to performance, well it's hard to tell. i mainly bought it for the diagnostic ability and the tire size adjustment, as i upgraded to 285's from the stock 245's. for our series of trucks, alot of people recommend troyer performance and the xcal programmer. although i 'm hearing a bit more positive about the edge programmer. hope this helps.
