I have one now for 19's but i want to go 24's. Can a calibration tube really make the car run right with 24's? I guess I just really can't see how it works. If someone can kinda elaberate on it I would appreciate it. I feel like you cant really trust it.. Thanks!

Like, I know they work, I just want to know how.. lol. Does it really take advantage of the injectors or just make it run rich?

Basically its gonna regulate how much air and fuel the intake will receive, when u have 24s the resistance is different then 19s so basically if u run 24s without the calibration ur losing power and wastin gas.
Hope that helped

So does the tube just trick the MAF into telling the computer theres more air coming in and to increase the fuel?

Well on any maf that is calibrated has the additional tube inside that senses the change versus a stock setting that is not set and unchangable. So it can be change between 24 and 30 also I believe.
But I guess u can say it tricks it.

EHow for the win...
A hot wire sensor works by passing an electrical current through a wire suspended in the engine's air stream, heating it. As the temperature increases, the wire's electrical resistance increases, limiting the amount of electrical current which can flow through the circuit attached to the wire. As air intake increases, the passing air cools the wire, decreasing its resistance and increasing the amount of electricity passing through the circuit. The wire's temperature is set to maintain equilibrium with the passing air, so the current increases only when the air intake increases. Likewise, the current decreases when the air intake decreases from the norm. These changes in current flow are registered by the engine control unit and translated into the relevant information for the ECU to make the necessary changes to account for the new intake level. These types of sensors are very accurate, however they are fragile. Any dirt or oil can contaminate the wire and cause an inaccurate reading.
Note the "passing air" part of this. The sample tube decreases/increases it accordingly.

They are called sample tubes for a reason.
Here is a plethora of information:
