Are chips or performance modules worth the money? Do they work? When talking about the Ebay resistors and modules.
1: No (Refer below for the why)
2: No
When talking about DSMlink.
1: Yes if you have an Eprom ECU and a turbo car
2: Yes if you have an Eprom ECU and a turbo car

the computer is trained to correct fuel based on airflow. so if you increase airflow, the computer will increase fuel. it basically counter corrects itself.

Resistors, whether harmless or not, have no place in major sensor wiring unless they are put there FROM THE FACTORY.
Don't be cheap, get a super AFC or some sort of REAL tuning device.
Oh, by the way, you do know running TOO LEAN will detonate your engine, right? Just a thought.

More information on why they won't work:

WOT settings are not considered "economical." that is one reason why the ECU leaves these alone.
think of your ECU almost like a tiny conscious robot inside of your engine with the sole duty of protecting the engine and making sure it runs correctly.
when you are at lower throttle percentages the little robot guy wants to maintain its factory settings because it was told those settings provide the smoothest operation and the best gas mileage. when you try to change these settings the little robot doesn't like that because someone told him those weren't correct. your settings, in his opinion, will not allow the engine to run the best and get the best gas mileage,,,so he changes them back. you do it again, and he gets even more pi$$ed and changes them back. you disconnect your o2 sensor causing the engine to throw a code (knocking the little robot out with a big hammer) and as the little robot falls he hits an auto pilot switch (open loop). now there are base settings with no one to get mad about your corrections and you can do what you please, but your check engine light will stay on. if you disconnect the o2 sensor while the engine is running until you see the check engine light, as soon as you erase that code, or unplug the ECU or battery for more than 1 hour, you will wake up the little robot guy and he will start messing with your corrections again.
at WOT the little robot guy (conscious, or knocked out) isn't tall enough to reach the knobs he needs to recorrect your corrections. he is also preoccupied with timing and emissions sensors. however, the more you run at WOT the more practice the robot guy gets and as soon as he notices the step ladder in the corner, he may just try to screw up your settings. always keep an eye out for the sneaky robot guy using tools like, AEM wideband, EGT, boost guage, AFC, etc.
the factory settings run a little rich for a few reasons:
1) protect the engine from teenager lead foots that beat on them
2) provide the smoothest idle
3) get good gas mileage, but not TOO good because then people won't spend as much on gas
4) allow people to run cheaper low octane fuel
5) allow for higher stock n/a compression ratios and still be able to run low octane fuels
6) run a little cooler
7) increase the number of applications per engine and engine control system
8) anything I missed :P
