looks like a good deal depending on price and location. in my opinion, you should purchase an HP Tuner. you can do some tuning yourself once you get a good base tune set up. you can also get the base tune from someone remotely, then make adjustments based off scans taken from the vehicle.

On a side note, it's great to see someone bucking the communist regime of california. keep us posted on your build, will be nice to see your progress.
