The Dodge Ram SRT-10 was manufactured in 2004, 2005 & 2006. The 2004's were RC only & in 2005 & 2006 they made RC & QC. The stock RC's run 12.9 @ 106 & higher depending on who is driving. Traction is a problem with these trucks. The stock QC's run low to mid 13's. They are heavier than the RC & again traction is a problem. The SCT is the only tuner that is programed for these trucks. By the way, Lostnwalmart, if you don't think they are fast, the Guinness World Record say they are the fastest production truck in the world. Sof if you decide to run one title for title be ready to walk home. Dom in Farmington, N.M. has an 04 that run 9.09 @ 148 in a quarter & pulls both front wheels off of the ground at launch. These aren't your 1994' 5.9, grandpa pickups.
