I know the stock fan is electronic, what I meant was after pulling the stock fan off and feeling the weight of it no wonder it robbed HP! What I was getting at is when I held the fan clutch in my hand and spun the fan; there was "a lot" of drag and resistance even though it was disconnected and the clutch was not engaged. Which led to my thought that it may have been a fluid drive clutch. Just kind of a thought to myself.

Anywayz.

I had my doubts about the aftermarket coils claiming more MPG's just was wondering if anyone had tested them or was currently using them.

I'm a pretty firm believer in OEM parts are best, but Motorcraft plugs seem to be pretty standard low quality copper core sparkplugs. I have upgraded everything I own to either NGK or Denso Iridium plugs and have always had excellent luck with them. I know different plugs won't persay increase performance, but an Iridium plug will definately last a hell of a lot longer and give more consistant performance over it's lifetime than a std. copper core. As well as a less likelyhood of fouling due to the harder finer tip and chance of coming up with a dead plug; better built higher quality.

Anyone have any other thoughts on the E-Fans??? Going to dial up the Temp. to 205 today and see if that helps. Also, info on the new CS seems so vague. Does anyone know if it retains the AVMPG or the IMPG features?? Is there any real performance advantage with the CS???? Remember I'm referring to MPG's!!!I'm always up for testing and troubleshooting, but if the CS with custom tunes isn't any advantage over the Gryphon with custom tunes I might as well stick with what I've got.

Oh yes, I did take it in for a 128 point inspection and 30,000 mile service. Had the tranny flushed, oil changed, fuel filter replaced. Other than that everything checked out! They did recommend a power steering system flush as well as fuel system flush and injector cleaning. Didn't spring for that yet, but it's in the back of my mind.
