i own a 04 6.0 with a 12" lift on 40" tires and 5.13 gears. i also have a banks six gun installed with the big hoss bundle. there's still a good amount of power even with the big tires but i want more. ive been thinking about getting propane injection for my truck from a company called stc performance in santa fe springs, ca. they say it's totally safe and i would gain a signifigant amount of power and lower egt's. what do you guys think?
