I see a whole bunch of them at www.autoanything.com. The specific list is
here (I shortened the URL):
Not sure if they are worth it, or if they are, which one to get. Has anyone
had any experience with these chips?
Any other ways to get some more punch out of a 5.7 Hemi in a 2005 Dodge
Quad 1500 with a 3.92 rear?

I used a Hypertech tuner on my truck. Best investment I ever made for this
truck. Huge improvement, slightly better gas mileage (about 2-3mpg), and better
transmission control. I should have done this as soon as I bought the truck.
Hypertech offers two levels of tune. I tried the max power tune. Didn't
any difference, fuel mileage went down, and it really pinged - bad on mid grade
slightly on premium fuel. So I use the mid grade tune.
Even with the mid grade tune I would get some pinging when I did moderate
(3500#), unless I had premium fuel. So I installed a 180* thermostat and some
Wetter. Now it runs even better. Last time I towed, I beat it hard on a
hot day trying to make it ping on mid grade fuel. Didn't happen.
Go to the factory web site and see exactly what the tuner will do for your
truck. Ads in most catalogs and sellers web sites list what the tuner can. But
of those features have an asterisk next to them, and the footnote says some
are not available for all vehicles. On my truck, the Hypertech tuner does not
changing the shift points or adjusting the speedometer for non-stock tires.
In short, buy any one of them that meets your requirements. It's the
and best improvement you can make.
Thanks Bob! Sounds like a plan. I like the write up on the Hypertech. I saw
another one called the Edge Power Juice, but that is pretty expensive and
would have to get under the hood to remove it if I were to take it in for
warranty work. Sounds like the Hypertech III is the one.
