hey there just wanted to know if these performance chip modules really work like tha ones on ebay or any kind of brands do they really give it more horse power or nah thanks.

They do work, more so in a car or truck with a turbo charger. If you have a car or truck without a turbo or super charger they also work but there is not as much of a power increase. What it boils down to is this: what does a chip do to get more power? Well, from what I am told the chip changes the temperature in witch the thermostat opens up so the engine always runs colder. Because the engine is running colder the cold start ejectors will stay on giving the engine more gas. More gas gives you a little more power. It also advances the timing a little. I'm sure the chip does a little more then what I am saying but honestly I don't think it's worth it unless you have a turbo on your car or truck. If you don't your never going to feel any difference seat of the pants. You will notice your gas mileage going to **** and heat might not work as good in the winter. Maybe someone else can post more technical info then I can. But honestly I don't think it's worth it. Johnnny

Basically, if you do no other changes to your car.. the chip won't do much, cuz the ECU doesn't have to do much adjusting.
The ECU will make adjustments to your driving style (hard on gas, ETC...) but like dssprophet stated, you won't really feel any difference. MAYBE slight increase in gas mileage, but not much
Once you start modding, exhaust, intake, cams, turbo.. etc.. then the chip will definitely help remap your fuel system.
I have read that Toyota already tuned the 4.7 V8 very well, and that there was very little to be gained from adding a chip to it.
On the other hand, a chip (GIAC) in my N/A 2.0L 1996 Jetta made a HUGE difference in the way the car drove. I'm not sure how many HP it added, but my wife noticed it BIG time
Waiting for a chip for my 1.8T Turbo Passat (+45hp) but am going to skip it for the Sequoia because I dont think I will gain much.
But first you have to invest in a K&N air filter ($), JBA headers, ($$), and a performance exhaust, ($$). A UniChip will be ($$). Unfortunately, no S/C are available anymore.....bummer.
That being said, expect to spend around $2700, (for professional installation of the last three components). You will definitely see a modest improvement in performance. Make sure to use premium unlead and if your daring, add a touch of tolulene for good measure. Nice!!
Throttle response is a blast! The truck really spins up between 3,000 and 4,000 RPMs with the aforementioned mods. Ya gotta luvit!
Well, I think the original question was in regards to the no-name chips found on places like ebay. I have never heard of anyone purchasing one, or installing one of those cheap knock-offs? From seeing them, it doesn't appear that they are even set up properly and are shown for models years that should have variation due to harness connection. I wouldn't trust a $60 chip on ebay or anywhere else for that matter.
If you want more information on chips, I think you may want to research Unichip. I know there is another manufacturer out there that makes chips for toyota, but I'm unfamiliar. From those who have used the Unichip on this site, it does work...but most people have them mapped for their modifications. Those who had the stock map were disappointed. Others seemed to enjoy the new map, but found that after time the computer would level things out, and it may require a reset at some point.
Unfortunatly I sold my Tundra and now i am looking selling my chip. If you are interested let me know...

Those ebay "Chips" are just resistors that you put inline in the MAF (mass air flow) wiring , that tells the computer that the air change is more dence (colder) than it is and that way the compuer will componsate throwing more fuel at the motor. This will give you a burst of fuel at WOT (wide open throttle) but also this will cause the motor to not accuratly burn off all build up in the motor.
I was wondering this too, but it looks like no they don't work at all. I was reading this article about it, and it looks these things don't work at all
With alld o respect... thes jet chips and performance modules and crap you buy at the "keep in a cool dry place" stores is a huge waist of money. I have seen really amazing things with the Dastek Unichip. I have one on my truck with the wrong map loaded and apart from it being a little rough I got a +- 20HP increase and this you can feel in the day to day drivability of the truck. Would I spend all that money again.... Probably not but would I buy a working used unit for less... Absolutely.

Hey thank for the article. Everyone should stay away from these things. they are junk
Well, from what I am told the chip changes the temperature in witch the thermostat opens up so the engine always runs colder. Because the engine is running colder the cold start ejectors will stay on giving the engine more gas. More gas gives you a little more power.
This is false. The thermostat is a mechanical device, the spring on the thermostat is deigned to open at a pre determined tempature depending on what tempature thermostat you have installed, generally either a 180 or 195 degree, so computer device can alter this. On older model 2.4L and 3.0L there was a cold start injector, not on the 4.7L, the old style "fuel inrichment" boxes would splice into the tempature sensor wires going to the ECM and could fool the ECM into thinking the engine was colder than it really was.
However the notion of more gas means more power is also incorrect. All more fuel does is flood the engine and cause you to blow black smoke. To generate more power it goes back to the 3 basics that an engine needs to run regardless of fuel injection or carburated. Fuel, air and spark and adding more of either one does not make more power, you need all 3 in proportional quantities to make power, hence if you have a supercharger or turbo which forces more air into the combustion chamber, adding more fuel is a necessity otherwise the engine will run too lean which will cause extreme heat in the cylinders. Fuel injection with all it's complex sensors and wires just takes the guess work out and the ECM compensates to run at optimal power 99% of the time.
It all goes back to the basics, but there is no magic box out there for $200 that is going to give you any noticeable power, Toyota engineers have already done this. Supercharging or turbo is the only way you will see a huge difference and dolar for dollar the biggest bang for your buck.
