So many idiots....

So, do these work at all?

I know chips for the computer can change the fuel map, and it does increase power, etc. Of course, you usually have to use 93 octane to see any difference.

These do anything?

For $6.99?? They do nothing.

A quality chip will run well over $100, usually in the $200-$300 range. A programmer that can plug into a car's OBD-II port and re-flash the ECU will be in the $300-$400 range usually.

The whole ad doesnt even make sense

Back in 1999 the founder of our company was about to purchase a performance chip for his 2001 Ford Expedition. This particular performance chip costs over $500. He purchased the performance chip and was satisfied with the results.

This is probably just one of those resistors you plug into your wiring harness to fool the car so that the computer thinks the intake air temperature is 70*F no matter the real temps. If anything, it'd jsut hurt performance, reliability ant fuel economy.
 
My favorite is the metal "tornado" thing that looks like a orange juicer. Restrict your intake and get 10 mpg! Or who knows it may just act like a restrictor plate and limit performance to gain fuel economy, but thats what your throttle is for...

The only real cheap performance and mileage improvement gimmicks that seem to be worth anything are some of the fuel additives on the market, but only because our fuel here is basically shit thanks to all the regulations and government mandated eco additives.

Typical government intervention: do something, it didn't work, do MORE of the same thing until it DOES work, etc...
 
..how's bout cow magnets?? wasen't somebody selling magnets to wrap around your fuel lines to get 20% better mileage??

uhh, one for my jetta is 500$+ a good one that is.
 
....and furthermore.....

You have to realize what the high chips are doing. They may be leaning out your fuel mixture, which *can* slightly increase your fuel economy or horsepower...at the risk of blowing up your motor. You never get something for nothing. Best case, with any of these chips, you'll be taking your vehicle from safe to the hairy edge, and throwing away a few hundred bux in the process. A $7 chip will do absolutely nothing.

Not necessarily. OEM fuel maps are extremely overly conservative. For example the stock ROM on the MR2 Turbo has an AFR around 8-9 at wide open when around 11 is more than safe. All it's doing is wasting fuel and power all because of our sue happy point the finger society.

What is worse than a chip are people who do intake or extensive exhaust modifications without retuning the AFR or at least double check it. A simple CAI can cause a lean condition on some cars, hence another reason for the conservative stock AFRs.

Always retune. At the very least, check with a wide band in car and run it down the freeway just for the peace of mind, especially on turbo/supercharged cars.

So you agree, you're just splitting hairs about how much more it costs. Obviously there are wide variations in price depending on the specific application.

"This is probably just one of those resistors you plug into your wiring harness to fool the car so that the computer thinks the intake air temperature is 70*F no matter the real temps. If anything, it'd jsut hurt performance, reliability ant fuel economy."
exactly....thats all they are....they have them for pretty much all cars, and they do in fact cause your car to run lean, i remember a story of a guy that had one on his rx, ran fine up untill one cold day, and bam. blew an apex seal because his engine ran too lean. its better to just suck it up with your not so great fuel economy, or just get lighter on your pedal and steadily accelerate instead of accelerating up to the speed limit in oh so many seconds.

"Our module will automatically tune your vehicles Air/Fuel Ratio Mixture to run at stoichometric levels. This in return will help you to save more fuel and since your vehicle will be tuned, you will gain horsepower while saving fuel!"
yes, tune it to run leaner....yep. and those electric superchargers are pretty funny too. i just dislike seeing alot of people think they can get something for very little or nothing....
