NON-Preasure Box (VanAaken, Edge J/A)???

[Buffalo]

I would appreciate your "expert opinion's", here.

I have an '03, HO, 6-sp. with a Magnaflow 4" exhaust & AFE ProGuard-7 A/F system. Other than that, the engine is stock.

In my reading on the Dodge/Cummins websites, problems involving preasure boxes (especially High Preasure) seem to crop up occasionally. Enough to cause me concern about their use on my truck.

BTW, I use the truck as a daily driver & for towing my 7500lb. trailer in the Western Mountain States. I don't drag race or sled pull. I would, however, appreciate a little extra performance when sitting next to a Powerstroke or Duramax at the stop light. Also, I'm interested in the small improvement in fuel economy some of these boxes provide.

At this point, it looks like my choices are between the VanAakin C3.2 or the Edge Juice/Attitude. Since I already have guages, I'm thinking the Edge J/A may be a waste of money because I'd be duplicating the guages. That leaves me with the VanAaken C3.2 or what ever else is out there, that I don't know about. I know about the TST but, that's a lot more box than what I need & it might be too tempting to turn it up into the "Danger Zone".

Those of you that have the VA-C3.2, or have experience with it, what are your thoughts about it?
I notice that it seems to only control injector pulse width. Doesn't say anything about adjusting timing. I have already done the "Tone Ring" mod on my truck. Would that act as the timing adjustment that the VA-C3.2 doesn't have?
In their advertising, they say that there is mechanical boost fooling available, or something involved with boost. Does anyone know how that works? They didn't explain it on their website.

Who has the best prices on these boxes?

Would I be making a mistake by purchasing one of these boxes & is there a better way to go, in your opinion?

Does the VA-C3.2 increase power & torque across the entire power band (from idle to redline)?

Thank You, for your thoughts & suggestions.
