Performance Chips / Voltage Stabilizers
I've been looking at some of the claims these gadgets make and find it hard to believe that I can get 50 HP and 3-5 MPG improvement for less than $60.
There is also a voltage system I was looking at, that says it improves gas mileage by 10%. So my question is, does anyone have any of these things installed? Are they any good? Do they harm the engine in any way? Any thoughts or links to existing threads (if any) that discuss this, would be appreciated. |
