Hey guys, I was just mentioning to my boss(hes a mechanic) about the gauges I was gunna install on my 02 WRX. I listed them all, and when I said, Wideband A/F he verbally slapped me and said it wasnt necessary, and (im still a beginner, dont make fun if I mess the terminology up) said that the stock computer wasnt map-able or tune-able (<- be gentle) and then suggested I get a water temp instead. Do I need a A/F gauge in order to get it tuned?/ Can anyone clear things up for me? Thank you very much!

If the side of the story you're giving us is true, your mechanic is a moron (or at least he shouldn't be trusted for advice when it comes to modified Subarus).

You don't need a WBO2 in order to get tuned (although, having one isn't a bad idea); the shop in question should have one to throw in the tailpipe.

I don't know how you'd confuse whether a computer was able to be changed or not...

Of course they are. Every car made in the last 20 years or so has a computer that can be tuned.

I suppose to some extent, but not entirely.. my brother's International truck checks its parameters against itself, and if anything has been tampered with it essentially throws itself into limp mode. Although the computer in that truck is far more sophisticated than one like you would find in our cars.

No, he is very good with a wrench, and a trustworthy guy, more than likely I am getting my facts confused.
wrench != computer

I've heard that from a lot of muscle car nuts. Definitely not true in the Subaru world. If he is good with a wrench, leave him have his wrench. Then go to somebody else to get tuned =).
