They're all "good" tunes

In all honesty, anything above 100 HP increase is merely going to smoke more on the bottom end when you first stab the go-pedal. Actual horsepower gains are going to be very small if any above that level since there are a lot of variables that limit your maximum horsepower increase....most of which are the stock injectors and the high pressure oil pump.
I typically don't recommend anything above 100 HP just for this reason. It's not likely that you're going to make more power than that without more modifications and any program level higher than that just ends up blackening the rear quarter panel without making more power.
How much in-town driving do you do? That would be my only question regarding whether or not I think you need the
Fuel-Sipper calibration since fuel economy programs are not intended to save you anything on a 40 mile long, 75 MPH commute down the interstate. Most fuel economy minded programs merely retain a near-stock shift scheduling procedure with some special timing and injection pressure rates at lower RPM. They're really not much "fun" to drive but help a bit in stop and go sub-50 MPH traffic.
Your best bet is to talk to Bill personally, tell him what kind of driving you do and what you expect. He can set you up with what would suit you best.
