100% agree! The extra $150 for the tune is worth it.There is a difference in my truck, with regards to spool up on the turbo. It does feel a little more lively. Check out Ed's site for specifics on the FICM repair, I opted for the 2 year warranty repair and the tune. I feel it's well worth the $475 spent, considering what Ford wants for a FICM.
With your permission, I'd like to add that last line to my website. So very glad to have helped you, cygnus, and Bismic out!!An electrical engineer huh? I am a civil and structural engineer with a PHD and I design the largest bridges in the world. If I am low bidder I get to build them. My F250 is a beast and there are 3 things that have added years to my life: my wife, my IPhone and Ed's tuned FICM. What are you waiting for?
Did you test the voltage after the truck had been sitting overnight? If not, that's the next step. While those symptoms sure sound like a FICM, the 'when cold' testing procedure is the sure sign.I recently bought an 06 super duty with a 6.0, and I am trying to determine if I have an FICM issue for sure. Mine smokes at start up and up until it gets warmed up. If I give it some throttle durning that time it really smokes a bluish white smoke. Hooked up a scaner and have ocassional drops in FICM voltage, down to 46.3v. Not totally sure thats the true problem. Have good voltage everywhere else and good connections as well. Any information?
