Hypertech Power Programmer 3

[bigblackchevy]

Hello All,

I'm thinking of buying a Hypertech Power Programmer 3. I have 5.3L engine, with TrueFlow CAI and Magnaflow CAT back. It appears that my computer isn't taking advantage of my mods and I was wondering if the Hyptech can help out, especially with MPGs.

Thanks!

It will help out with power, improve shift firmness (I actually like to feel it shift), but I saw absolutely no mileage increase. You can also adjust your tire size if you have non-stock size tires, read codes, etc.

Check on e-bay for them. Usually you can get them cheaper, just make sure that it isn't VIN locked.
