bean_8044 Posted July 21, 2004 Share Posted July 21, 2004 Well, its your car so you can do with it what you will, but i would never let that thing come anywhere near my car. It will probably work and give you a few extra horsepower(5?), but its not worth it. If im seeing it correctly, it just intercepts the signal from your AFM and lowers or raises it accordingly to dump in more or less fuel.

bobsvilla Posted July 25, 2004 Share Posted July 25, 2004 if it is what I think it is, they sell you a small 1/4 watt resistor (Radio Shack 50 cents) and a wiring diagrahm where to install it. It fools the mass air sensor to thinking you have more air, so it dumps in a little more fuel. Quote Link to comment Share on other sites More sharing options...
soarerTT Posted July 30, 2004 Share Posted July 30, 2004 i was wondering if anyone new the downsides to that, such as you get worse mpg? or bad for engine? you say is it worth it, well i was wondering wat what it would be costing once you installed it? thanks Quote Link to comment Share on other sites More sharing options...
