I'm going to agree with Thomas on a lot of his points.
To answer a few of your questions.
- Yes, you can get a Gryphon for your truck that will include the digital gauge.
- Yes, you can get a Gryphon with three programs loaded on it. You still have the capability to program the truck back to stock so in essence, you really do have 4 tunes in the end.
- The gryphon is NOT a "turn it on and off" kind of product. It actually reprograms the truck's powertrain computer for each separate tune. It takes time to actually change the programs (5-8 minutes at times) and they can only be changed while the truck is not running. Once a calibration is loaded into the PCM, it is there ALL THE TIME until the Gryphon is used to reprogram it to a different setting.
- The display pod SHOULD come with the Gryphon. It will be black and can be painted to match the interior.
Now, to add to what Thomas said, the Phoenix module (or FU package) is usually preferred by most people because of it's "shift on the fly" capability. This means that one of up to six calibrations can be selected at any time (instantly!!) while driving to best suit the conditions at hand. There is no waiting and there is no fuss. On the downside, there are no gauges included with the Phoenix module. A pyrometer (EGT gauge) is an absolute necessity and requires a thermocouple probe to be mounted in the exhaust manifold. Similarly, the Gryphon will also require the same procedure to render the EGT monitoring function operational.
The human brain much more easily recognizes analog needle movement as there is a
comparitor. The brain can interpret an actual point in relation to a maximum point much more easily on a gauge face rather than trying to read a digital readout and mentally compare it to where that point is in relation to a value that is not seen.
It's personal preference, but I hope that this information helps you out.
