Rollback benefits
I have a 2007 F250 6.0L with the VXCF9H7 ECM calibration, and TQCK0HZ TCM calibration. My Edge Insight CTS wouldn't pull anything on the FICM (or I just don't know how to make it do it).
What benefits would a rollback and new FICM strategy get me? I've read the whole page on this site and the dyno graphs show the new FICM strategy on an older ECM program, but I couldn't find anything about the difference in ECM rollbacks, specifically on an 07. The forum fact is that 2007s are somehow different and won't benefit from stuff like this the same way earlier trucks will, but what's the real deal?
