Without getting into opinions on the website mentioned....I have one (not the Ebay one, but same thing). Early on there weren't any "no code" tunes and depending on the truck, usually between 23-27psi the PCM will tell the engine to start cutting fuel (defueling) to limit boost levels and sets the check engine light for a few minutes. If your truck is making boost levels up in that range then it can be worth it. I have one on my truck. All it does is bleed off any extra pressure over whatever it is set at so the MAP sensor thinks it's under factory set boost levels and it keeps the truck from defueling. I run 28-30 psi right now and the boost fooler has been working great for a few years now.
One other option is I know that some tuners these days are making "No code" tunes and it pretty much eliminates the need for the boost fooler.
Oh yeah, one more thing...You can probably make one for cheaper than that. Mine is just a air regulator (like one off of a shop compressed air tank) and a few feet of line to connect it. Just make a few runs and set the regulator and you should be good to go!
