I also have an FS450 in my 150/150. I agree, it is one of the best devices to have. I do not have mine connected to a GPS but I find it quite easy to look at my GPS's ETE and the time remaining on the FS450 to get a good idea how the flight is progressing. I look for a time remaining between 45 minutes to an hour more than my ETE.

The beauty of a fuel flow computer like the FS450 is that you can readily tell if the situation is changing. A couple of years ago, I was flying home from Clinton. I stopped in Harlan, IA for fuel and was trying to make it from Harlan to North Platte, NE, a distance of 245 nautical miles. Things started out well and at the halfway point, things still looked good. After the halfway point, the winds started changing and the times on the GPS and the FS450 were converging too much for my liking. I made a precautionary fuel stop in Ord, NE.

An FS450 is a great device and I highly recommend it.
