Turbo upgrades are a waste of time without exhaust work.
Are you running stock exhaust?? If so, the first item I would address is the downpipe... get a 3" in there. This won't give your truck more HP, but the turbo WILL spool up faster and give you the go-go lower on the RPM band.
Try to do this with someone who has done this work before, because you will have to bend part of the firewall and heat shield to make clearance. My truck still rumbles at negative driveline torque due to the exhaust downpipe rubbing.
