they're basicly a power programer like Banks and Bullydog for Diesels.  They adjust the settings, tricking the computer into providing more power.  As far as how well those work... you got me.

But Banks and Bullydog do increase the power on diesel.  And the fact you can shut it off from the one on 4x4parts.com means you can atleast keep some decent mileage. 

For the intake and exhaust... it wouldn't be a bad idea to have those done first.  This will open the engine up more, enabling it to use that extra power the programer is pulling out.

Man.... 

1.) I noticed a slight increase in my gas mileage when I did the intake mod + K&N filter, with a muffler.  But you won't gain much unless you throw on a Tonneau cover.  That's when I noticed the biggest gain. 

2.) I have no idea off the top of my head any numbers of people getting with their 3.3L  But I'm pretty sure for the MAX numbers possible, it was achieved with JWT parts, intake, exhaust, gearing, and the 91 octane with supercharger.  If you want to keep your gas bill low, check into those 4 items I listed first

3.) I've heard nothing about usuing Acetone as a fuel additive.  Though I used to get such good gas mileage with my old frontier. (one of the reasons why I wish I hadn't traded it in)

I USED to have a 4 banger (traded my baby in)  And I wish I hadn't, cause she got such good gas mileage.  I could drive back and forth to work for month and half before I had to fill it up (work is only 3 miles away) and that's even taking it on a 30 min trip once a month to Sturgis.  Realize the tank on the 4 bangers is only 12.5 gallons.  That's REALLY GOOD mileage for a truck.  And I used 91 in it because I found that gave me the most power, and lasted longer than 85 or 89.

As for the bed cover, the first thing I noticed was a higher top end speed was achievable.  I went from 104-115 top end just by having that bed cover on.  LOL  Plus I noticed I had a lot better gas mileage, about 5-8 MPG more on the highway.  It's amazing what that thing did for me. 

For the bed cover, I had a roll top, requires a lot of maintenance.

Click on the frontier, and go to page 2 or 3 i believe.  that shows most of the stuff about the cover, maintenance and install.  It only takes a hour (though the place that installed it said it took 2 hours... I don't see how) 

Mine caved in from a HEAVY snowfall.  Not your normal 6 ft of dry powder, this was 4 ft of WET snow.  That was the reason why I had to take it apart.  It does flap when driving down the highway... but honestly I could never hear it over my subs
A friend also cause a small dent leaning on it to close my back window.  Look at my entire site of the truck so you get the idea.
