[Power Hungry]

Here's some thoughts...

One of the things we've seen with "aggressive" chips is that the pulse width is opened up to a point where normal injector operation can be compromised. Depending on the targeted injection control pressure, excessive pulse widths may actually cause a reduction in performance and ultimately a loss in injection control pressure, especially when running modified injectors.

Datalogs have shown that for most vehicles the factory pulse width settings work quite well and performance gains can be had by increasing the injection control pressure to a point where there are marginal fuel volume gains along with improved atomization. A small timing advance is also inherent with raised injection control pressures, reducing the need to aggressively modify the Start of Injection control tables.

Tuning for these engines is always evolving and we know more and more each day about what it takes to make reliable power. Along the same lines, there have been vast improvements in hardware to meet the ever greater demands of the enthusiasts. This coupled technology has pushed the 7.3L further along than anyone though possible just a few short years ago.

In any event, it's safe to say that considering how fast technology changes, the tunes you had 3 years ago are almost surely outdated now.

Take care.
