Do I need wideband controller I've been searching for the past couple of days and can't find a definitive answer. Do I need to run a wideband controller if I am not going to be changing the motor mods around? Its a stock lq9 with a procharger. Its going to be dyno tuned, so if I am understanding correctly, I would need one to tune the A/F ration myself. I know with a gauge atleast, I will know what my ratio is. This is in a chevelle. Thanks guys

If you have a competent tuner and they will be tuning it with all modifications done, then no you do not.
But, given how cheap they are, it is a very useful piece of information to have available all the time.

I think when it comes to FI you really need to have one installed for monitoring purposes. If you want to wipe out a FI engine an improper AFR is a good way to do it.

Thanks guys. This into going to be my performance car; my next one will be. I don't trust myself doing tunes myself, FI is new for me. I'll stick get the wideband controller to stay safe and the bypass valve.
If you have any gauges at all I would suggest boost and AFR. Like said above just good as a monitoring device if nothing else.
Those are 2 things that you should keep an eye on, WG can fail causing boost issues and/or fuel pump could go bad causing a lean condition just a couple instances where they would come in very handy.

You could plug in and get NB data but of course this is less useful.

I have very little experience with FI motors. Only time I've ever used an AFR gauge was when I put one in my 67' nova with a small block. It was very useful in tuning my carb. I definitely see the benefit even if only to monitor. First time going boosted on anything as well so I'd like to know the system is doing what is supposed to.
