it would be saffe to use it with a real wide band Air/Fuel guage, or go somewhere that can measure if ur running too rich or too lean dont do it without knowing whats going on lol, my firent has this and he says it works fine but doesnt do much

 

right i just wanted to kno if it could be hooked up to a scion i already have a wideband but does he know the correct a/f ratios he should be running.....in example at wot (wide open throttle) a 12:1 a/f ratio will be most beneficial (most power) cruise and regular street driving should be somewhere between 14.5:1 and 15.5:1 where as 14.5:1 will give you better throttle response and 15.5:1 will give u the best fuel mileage....any leaner than 15.5 on most vehicles will cause driveability issues
