hey this is Mayday from TN. i have an 04 Titan bought it about 2.5 yrs ago. It has mods that i have no idea about, front leveling kit ,air bags on back, after market exhaust and such. I found that it runs more like a mustang than a truck. I pull an ultra light camper and am dissapointed in the low end tourqe without really putting my foot in it, i am cosidering a TB spacer and maybe a cold air intake Need advice please!! What i do love about her is running a twistie road, shifting manually and listening to the pipe. Heads up i am computer challenged ,forgive me.
