The AEM wideband comes with the o2 sensor and gauge.

Oh okay cool. I've read that forum 3 or 4 times all 40 pages. He didn't tune his PCM or run a wideband

The 4.0 can handle a 5-8 PSI with an AFPR that raises fuel pressure with boost pressure. It's not a spectacular way to do things but if you have a wideband then it is fairly safe.

As far as timing, as long as you run 93 octane you shouldn't have an issue with the stock timing maps but you can always put an MSD box in or something.

The 4.0 can only put out a certain amount of fuel pressure. It's not like a diesel than has a huge window of pressure. Would I need an MSD? Will it be super affective? I may even run even higher octane haha
