yes eric, this is for all years...each year model truck had different strategys.the earlier ones are alot better than the later ones..now he can not put a 03 stat on a 06 or 07 truck but he can roll back the current stat to a early one.like we put my truck back to the strat it had the day it rolled of the factory line but later we changed it to a tec 3 strat now..lil better fuel and power on the tec 3...its well worth the investment ...just my two cents
