Did you know?ConsumerReports.org picks the 2009 Chevy Avalanche as the truck of the year.

Does anyone know much about whether or not the jet stage 1 or 2 chips work? I have found some really decent pricing on them and am just curious whether or not they will do the trick for me.
A lot of people use handheld tuners like the Predator and Hypertech. The advanced guys for for the HPTuners or EFLive. Do you have a link for the "chip" you're talking about?
Is it a chip or a handheld programmer or device that plugs into the OBD-II port?Chips are pretty much not used for the OBD-II vehicles that can be reflashed vice having a chip inserted.That said, I'm not familiar with JET reprogrammers of any kind. I've used a Hypertech in the past, and currently due custom tuning with the HPTuners package. Most of the canned reprogrammers are pretty good as long as your mods don't include things like an aggressive cam or forced induction.
The website itself says performance module, which would be a chip.
I sure do, http://www.autoanything.com/performance-chips/61A1777A0A0A3336822.aspx , its a little over $100 cheaper than the handhelds themselves is the only reason im looking at them.
The electrical engineer in me would disagree, but I quibble.I'd check on ebay for this if you're good with getting one used. In general, the programmers go for about half on ebay for what they go new.
Having had my ECM out of my Avy before I'd like to see the actual one that goes into an Avy. It isn't going to be as easy as the video they showed on the ford. Other questions to ask yourself before purchasing;Do you ever plan on changing the tire size, intake, or exhaust?This programmer is pretty much limited to what it will do. If you add an exhaust or CIA after doing the chip it won't be accurate any more. It cannot change tire size also.IMHO, it's worth the extra $100 to go with a handheld as it's much more versatile and you can change settings as you change things on the truck.
The only thing i guess i have with ebay is whether or not they really have only been used once. Cause it would have to be unused right?
Looks to me like it only does its thing when plugged into the OBD port. Web site said you go back to the stock tune by simply unplugging it. I'd think that it wouldn't matter how many times it was used. Should probably double-check that there isn't a limit as to how many times it can be unplugged and replugged.
I actually already have all of that different, 20 inch wheels, dual exhaust and k&n intake. Thats why i was asking opinions. haha. I really want to get some more power but i want to find one that is truly worth the money and will not murder my mileage.
Making adjustments with my predator after installing efans on my '04 I could get 19.5mpg highway out of it running between 70-75mph on fairly flat ground. Mine's a 4x4 also. There's lots of parameters you can set with a Predator instead of settling for one tune. There's preloaded or "canned" performance tunes and you can even modify them to your liking a little more.
Now that one would seem worth it to me, haha. I am getting 16.2 mpg right now with mine.
We just got back from a trip with the wife's '05 4x4 and it got 17.2 with nothing more than a drop in spectre air filter in it. It's got heavier than stock tires on it so that might have contributed to the lower than expected mpg on hers. Mine now has a 3" lift and bigger wheels and tires and I haven't hit 15mpg yet with it since the mods have been done to it.
Okay but the same does not apply to handhelds though does it? I know about alot of engine mods but i have usually worked on pre-computerized stuff so idk much about the computers and all.
The handhelds generally flash their program out, after reading in what is in the vehicle already. They cannot be used on another vehicle unless the process is reversed - the program that was previously read is flashed back out over the non-stock tune flash.
