Really? Why? Can you please explain.

From my unserstanding and little tuning experience an widebend O2 is a must have while a EGT is a nice to have, but not needed for tuning, just monitoring.

edit: I don't have an EGT gauge yet so I am curious to know if there is another aspect of the tuning I should be looking at. I'll go through Gadgets tuning instructions again, but I don't remember him mentioning anything about needing the gauge to tune.

Check out urdusa.com under tuning for the instructions in case you haven't yet.

basically, our engines make peak power at ~1450 degrees at wot. you want to get your a/f ratio perfect while keeping around that temp. you can have a good a/f ratio but still get into the 1500+ degree range and melt things

gadget can explain it better i'm sure

ok then i'll go with the wide band o2 meter. hey gadget do u think you can give me some tips on how to tune a s-afc for my truck when i buy the wide band from you.
maybe u can help me out with this i bought some injectors from davidtaco a while ago and they are off a lexus they are green top. do u know the what size they are.
i can't remember if they are 305 or 315cc .

You can download the U-Tune tuning guide. The same techniques will work with the AFC.

I have no idea about the injectors. I would never install any injectors that are a mystery. Get them cleaned and flow tested so you will know exactly what you are dealing with. It is cheap insurance as compared to a smoked cylinder.
