STFT mess

[FiestaSTy]

I recently got around to installing the necessary hardware to support the Dizzy Stage 2 tune I have had sitting on a shelf. Before sending him datalogs, I reviewed his website where he says STFT should settle down to +/-1% within 100 miles or so. With 175 miles on since loading that tune, my Cobb AP still shows STFT at -14.84/+9.8. I notice it settles down to 0 at highway speeds as soon as I come off throttle and hear the BOV vent. Mods are limited to Whoosh V1 FMIC, Turbosmart BOV, drop in filter and 1 step colder plugs from Ron@Whoosh. I need to get this tracked down before sending datalogs to Jason@Dizzy. What are my likely culprits? Thanks all!

That’s for the Mazdaspeed tune. Ecoboost STFTs are all over the map.

Wait, so you're telling me (an illiterate moron) that the words "Mazdaspeed customers: Please perform the following vehicle-specific checks" means it doesn't apply to my Ford? Seriously, how the hell did I scroll right past those huge, bold letters? I am such a doofus.
