Do you need more than what the SCT X4 already gives you? The 7015-PG allows 6 monitored selections on the screen at one time. It also datalogs fine for me to get revisions.With that OAR you should be good to go. Just a suggestion, although the tuner will allow you to monitor quite a bit, and you can use a laptop to datalog for tune revisions, etc. it is cumbersome to use unless you are getting ready for those revisions. I recently purchased the Banks iDash Supergauge/Datamonster and love it. If you set it up for the Ford ECU, it has what you need and you can run so many different combinations of data on the screens/gauges at once it can be overwhelming. On one gauge I have OAR right at the top as well as other fueling data below. It will datalog as well with a simple SD card and converts it all to .csv. $295.
Unleashed gave me a config file to use to datalog and i have OAR and a few others monitored to watch what it is doing.
My X4 is mounted right in front of the "oh shit handle" on the driver a-pillar so its within view while driving but out of the way for looking at the road.
