LIke the others said, it just depends on the price. With you having a 2011, you would need an InTune DCX or an i2...the regular Intune will not work on your truck. Hemifever charges $125 for custom tuning if you supply the tuner, and last I knew, JG was charging $175 for his custom tuning.
If you can get the used one cheap enough, know it isnt VIN locked, and dont mind not having a warranty, then that isnt a bad way to go.
