Dare I say...one more question??(naaa ain't ever gonna happen) Depending on what I can learn from my esteemed fellow 'strokers in their infinate wisdom and knowledge I will be guided in my quest to seek power and (maybe not) fame for my most humble E550 Beastie. I'm gonna be getting a chip from Jody...thinking about 3 pos...40/60tow, 80econ. However...the problem I think I'll be having is one of high EGTs. There was an old chip in the truck when I bought it last year(unknown to me at the time) and after installing the guages I reinstalled it (after Allegheny Ford found it and sold me a new pcm...which I didn't need) anyway..to make a short story into a lengthy novel, while it did seem to increase the power, my mileage went down about 10% (of course that was loaded to 19040lbs and before I plugged the drain line on a leaky fuel drain) but that aside...my EGTs would hit into the 1400's when pulling a steep grade or just pushing it hard. Average driving..ie "straight and level" she'd hover around 800-1000. Mind you, I drove this Beastie for almost a year, without guages and oblivious as to either the presence of the chip or the elevated EGTs and as far as I can tell, she suffered no ill effects. Also consider that I'm not inclined to be "heavy-footed" and on the freeway, usually keep her to around 63..even when the speed limit is higher. I drive for a living and the fuel costs come out of my pocket so I usually opt for better economy, and 63 seems about optimum. Also looking into possibly, when (if) free funds become available, of swapping the existing 4:88 gearing to something like 4:11. I drive an average of about 55 to 60k miles a year, and at nearly 3 bucks a gallon, I don't think it would take long to recoup the costs involved. But..back to the prime concern..EGTs. The high temps (along with the consistant SES and P1211 code) scared me so I promptly pulled the old chip, but I really miss the added power (I was passed by an old lady in a wheelchair the other day...quite embarrassing..especially as she flipped me off for going so slowly..LOL) The longest I expect to see these kind of temps is maybe 10-15 minutes while climbing grades..is there a cheap, DYI method of lowering them to a bit less frightening level? Mind you this is an E series...ergo, an aftermarket intake and/or 4" exhaust won't fit, and I can't seem find anyone anywhere able to fabricate one (or the other). Your help, assistance and guidence here would be a great help...Thanks guys
