hp mod for iat sensor, do they work?

[popo]

I have got a horse power mod that is supposed to go plug into the iat sensor to register cooler air. I plugged it in and my stanger started but quit. Do these mod's work? If so what am I doing wrong? I have a 2001 v-6 mustang with a 3.8. Please help I would like to have some extra horsepower.

These systems do nothing but cause your motor to run slightly rich and will do nothing good for the car. It actually does cause harm to your motor, because if your motor runs at a different a/f than optimum, it causes greater wear on the motor....Take that CRAP off.

true dat.......you're gonna have to spend money to make power. You get what you pay for and something off of ebay for $2.99 with free shipping won't do jack for you.
