Gryphon vs. Phoenix + guages...

[muns53]

So, the nature of my question comes because there's a bunch of people out there I hear saying analog guages are the way to go, etc. But, I'm not a purist about most things - I usually try to seek the middle path.

My application for a tune is to juice my truck up a bit without doing any long-term damage; increase the mileage (although I will mostly run on veg and not diesel, but still... nice to have the better mileage... less oil to filter); get better on/off ramp and passing power; and just have more fun with my 8000lb toy! I also will tow a 5K-ish trailer (with veg oil on it) from time to time on long trips - and envision towing a family camper at some point (I've got four kids). I also drive up/down hilly terrain all winter to & from skiing and all summer to & from hiking/camping/etc. Also, I get pesky codes in my truck that I would like to read & clear on a regular basis - mostly as a result of opening up the airflow with my intake/exhaust and stomping on it once in a while for fun which sets up a boost alarm.

So, I'm trying to see what's the downside of going with the Gryphon - I'd get my guages and tuner in one package - plus a code reader - plus three power levels and the ability to play with shift points. And I could do it for less money than a Phoenix+guages or other tuner+guages setup.

Do you guys with the Gryphon find the three power settings limiting?

Do I need to put in a boost-fooler? If yes, does that impact my ability to get an accurate boost reading from the Gryphon?

Thanks for your thoughts!
