Anyone familiar with these? It sounds a little too-good-to-be-true, but that has pretty much become my natural reaction to these online instant-power devices. Is this thing for real, or just another scam?

 

Well this says up to 25% increase in power.

soo you have 150hp...that would be a 37.5hp gain.

Lets say just for fun that they are inflating specs by half.

so it would be a 18.75 hp gain. Does that sound beliveable to you?

it sure doesnt to me.

 

wonder if those really work

 

I dont know my head tells me that theres no way to 'plug-in' that kind of horsepower (on a gas engine anyway) but you can't just completey lie about what your product does

 

Very minimal gains if any on stock NA engines.

 

The only way you would see gains like that is with forced induction.
