For pulling definatley change the exhaust. A 4" will drop your Egts while pulling. To further reduce the Egts you can also install a downpipe. I would get a programmer as well. You do not have to go all crazy with the power just a mild tow tune.

When you get a exhaust they usually come from the downpipe back. The Downpipe is the piece that goes from the turbo down behind the motor the rest of the exhaust hooks to.

Like said above, an exhaust including the downpipe and maybe a edge tuner that comes with a cool monitor so you can watch your temps etc....

since you have an LB7 downpipes aren't out yet...there is one in the works but its not really necessary for your truck.

i would do an exhaust, tuner and gauges to keep an eye on boost and egt

edit: darn tyler beat me to it...
