    Cheaper mod for more hp

    So, I'm sure you guys have seen devices like this before. I have something similar that is made for my truck that only cost me $30. What the device is doing is changing the resistance in the Air Temperature sensor. The one I have is a fixed resistor so that in the hot months you put it on and it provides winter like performance. I'd be highly surprised if you could get 15% better with it. But during the summer it would be a good add on if cheaper.

    Might gain a little, but you can add all the extra fuel you want and of it doesn’t have the ability get extra air, it’s going to hurt performance from running rich.
