The AFR gauge serves it purpose on a turbo car. Especially if it starts acting weird. You know immediately if it is mechanical or fuel related. The best thing I ever did was install the XD-16. If for nothing else, peace of mind.

Nothing useless about the wideband gauge. It's probably the most useful gauge you can have.

 

I was driving a car with a dual pump setup and a line popped off of one pump while in boost (36psi). I credit the motor surviving to seeing a 13 appear on the wide-band and letting off of the gas. Having an unobstructed view of the door ajar light wouldn't have helped me much.

 

Oil pressure, oil temp, water temp, wide-band AF, and boost are all valid gauges for a street car. Hell, I don't even mind a voltage gauge really. You could blow a motor if your battery output dropped too low and your voltage corrections aren't set correctly or are non-existent.

 

Fair enough, but there's no way I'm going to see what an A/F gauge is doing when I'm driving, especially when I'm doing the kind of driving that's going to cause me to get into boost.

I'd much rather just trust my tune and componentry.

 

I think that spot would be good for a boost gauge. Omori has a smaller 45mm one that would be cool there.

What A/F gauge and what other gauges do you have or are planning?

Innoavate's gauge is -3/4” thick, so it's possible to surface mount somewhere.

 

Currently have Boost and EGT on A-Pillar. I need suggestions for the location of the Innoavate's XD-16 digital gauge.
