the factory oil pressure gauge happens to work very well

factory water temp gauge can have variations as it does not have a large swept area - afternarket gauges will give you more precise readings, but unless you do heavy track days, I personally don't feel it's worth it.

Wideband AFR would be the oil one I'd get, followed by oil temp, again, if you do heavy track days or live in a very hot climate

Up until now, when I got my Racepak cluster, I had zero aftermarket gauges in my car FWIW, and it's heavily modded and built

 

so, you're basically saying it's useless for my situation?

i mean, i intend to go FI in the future (sometime next year). and i thought i'd have this gauge now, and later get a boost gauge when installing the SC.

enlighten me.

 

thats ricey bro, save your money on the gauges until you have a turbo kit.

 

yup save the cash and FI quicker
