The whole deal with the issue of running lean is most often an issue of location. At elevations above sea level, less oxygen means less fuel required for the right mixture and so on, stuff most of you already know. Basically what I'm trying to say is that for the 3.4, running lean isn't an issue for people at any sort of altitude. I did notice that we have a lot of guys on here from Texas though and in that case the 7th injector would certainly be a good decision for the lower elevations. With that, running lean should never be an issue.
Being at higher elevation reduces boost. Some at sea level will get 8psi no problem. Maybe a touch more. Some one at elevations higher wont.
Case and point my dads 08 has a TRD SC plus the URD
smaller wheel. Till only makes 6psi due to lack of it in general up here.
