Could be.
Could also be that the DSII ignition module (aluminum box on the drivers side inner fender) is not retarding the ignition timing while cranking.
This is a feature of the factory (Motorcraft) boxes and NAPA Echlin for sure, but I have heard that some of the cheaper aftermarket modules don't have it.

Back up to 10 and see what happens. I'll bet your issue clears up.
Also, like previously mentioned by ArdWrknTrk, check your module for brand name. If it's not Motorcraft or the NAPA Echlin line, you might not be getting the benefit of retarded timing while cranking.
Do the timing adjustment first. It's free, and will help you pin down this problem to a timing issue. Then check your module. If it's a cheap Chinese or off-brand unit, you might be able to re-advance your base timing for it's performance/MPG benefit by getting a quality module.
Let us know what you find.

This page has a nice color coded schematic showing the how the retard function is set up.
http://webpages.charter.net/1bad6t/duraspark.html
Farther down the page are two links for schematics of different MSD setups with the DSII.
Hope this helps.
