Do I need to get wideband o2's to get a decent tune?
I've been having problems when she is cold like bogging and won't start right away. When she warms up she is fine. Don't get me wrong It is much better then is used to be. As long as it is warmed up.
wideband o2's assuming you have a wide band air/fuel ratio gauge to go with it, comes in really handy when tuning.
you don't need one, but you need one to get the best out of tuning is how i look at it. You can go buy the seat-o-pants meter, but thats just never accurate enough to tell you if your running lean or rich.
as far as cold starts, the o2's don't start working until they get to certain degree. i think its over 200*. So they aren't functioning properly until then.
Could 19 lb. injectors cause a little tick or lifter like sound in my engine? It might be an exhaust leak also, I having a little trouble tracking it down.
