sure you cant use the stock narrow band for tuning purposes where precise voltage is required but it will read the difference between rich and lean. the "disco light" will let you know if you need to let off the gas in cas something went wrong (leak, bad pump, bad injectors, etc)
its illegal to have a mechanical fp gauge in the cabin

All it tells yo uif you are rich or lean. Doesn't tell you if you are running 14.7 or 12.5 A/F. Use it if you want. I bought my POS Autometer and found out the hard way. Good thing it didn't cost me a fortune.
Plus it only reads when you are at WOT. Which does nothing for you at idle or part throttle. Yeah you tune you car at WOT, but you don't drive your car at WOT.
I have since moved up to a wideband and it tells me everything I need. Every change in the A/F at every throttle position. Idle, part throttle, WOT, you name it.
But hey, your car, your money, do what you want. I was just merely giving you my 2 cents.
