I read the article, thats how I found this forum,
. I have a 04 PSD that got new heads under warranty a year ago (and a PCM reset), and was at the shop again for a wiring harness warranty repair thus summer, and again the invoice says "reset PCM". To be honest I dont know if it runs worse - it always seems to run fine. Over time I kept adding goodies and never got a real good MPG baseline. Would I see improvement if got my FICM reset to the original factory setting , or are these not related ? I get 14-15 mpg with my SCT on the 100 HP setting, so I cant complain.
Thanks,
Tom
