Any recommendations on running two separate wide bands for the HP Tuners set-up? Not sure I see a need but I'm a sucker for symmetry.

A pair of aem 30-0333s

That's what I'd do ^

I noticed that the factory CAT sensor is on the left down pipe so I'll most likely go with a single AEM on the right down pipe to start with.

Factory has sensor on both banks before cats and sensors on both banks after cats.

schpenxel, should you run two wide band sensors ?

There's not really anything you can do to adjust one bank vs. the other, so I guess the only purpose would be to see if there's an issue. Those types of issues (i.e. injector way out of balance from the rest or vacuum leak) typically show up as big fuel trim differences anyways, so not sure an extra wideband would really be worth it

I usually just run one in the drivers side which is supposedly the leaner bank. Probably better idea to run it in the X pipe so you get both banks but I haven't gotten around to doing that

I mean.. more data is almost always better.. but you can't really do a whole lot with it if there isn't anything wrong and one bank is just a little different than the other, and there are other ways to spot common issues, so I don't think it's worth it for most regular people. Just my opinion though, I'm sure some will disagree.

completely. Besides not being of much use in a tune function BC you cannot fuel or time half of the motor with only one MAF and one VE, it would be a little crazy to impossible to read out two WBs simultaneously. Difficult/messy to do with analog WBs and Dashlogic; or, you'd need two AFR gauges.

Might only serve to more quickly ID a bad injector or misfire if P codes haven't already caught it, and manifold vac leaks will impact both sides, etc.
