i was wondering if any one could tell me the egt's they recieve when running the super chips 1705 on any of the three levels i have not purchased any gauges yet just got the programmer and was just wanting to know
I do not want to sound sarcastic, but if you do not have any gages then whats the point in knowing the temps since you have no way to compare or contrast your own trucks' readings.
my guess would be so that he can ballpark his egt with equiv mods so he knows weather or not to latch on to his fishing boat or his garden cart for fear of hurting his truck.
Well eri64, I do not have a programmer on my truck, I have a chip so my EGT's would be irrelevant in this case. BTW why didn't you post your EGT's? Doesn't this omission make your post just as much of a "waste of time" as my post. At least both of our posts were on subject. Both of us started off with a disclaimer by stating we were not being sarcastic. I for one was not, and I believe Quadzilla wasn't either.
cowboy's ford; You will need more info to make a good comparison. Such as what year truck you have due to several different engines offered, as well as some were not inter cooled, axle gear ratio, and other mods like exhaust, injectors, and intake will make a difference in EGT's, as will pyro probe location.
Cleatus12r, could you please explain your theory dealing with elevation? I'm at very high elevation and have wondered about this. Seems easy for my truck to reach 1150 degrees post turbo ('96 Tymar, downpipe, no cat, no chip) driving over mountian passes.
1150 POST-turbo?! Isn’t that, unh 1450* or so exhaust temperature? That would be over recommended safe temps. And to address your question about elevation; the air is less dense at higher altitudes. At sea level (mostly, here around Seattle) it is hard for me to get above 1200* pulling up the passes. But when I was driving through Utah last month it was no problem at all to push her up to 1250* going over some of those 7000 & 8000 foot passes.
I get the following temps with mine, Pre-Turbo, NO CHIP (some info may be more useful than no info)
Empty, constant highway speeds: ~600-700F
Pulling ~9000lb 5er, constant highway speed, Turbo at ~5psi: ~900F
Pulling, two lane road, floored, passing Grandma, Turbo at ~15 PSI, ~1100-1150F (yellow zone, don't keep it there very long)
I expect that getting a tuner chip will up all values incrementally including turbo boost and EGTs with each level of HP increase. This tells me that having a chip would be nice but that I'd better get on it intermittently to allow the system to keep in cool enough operating range or else plan on buying a new turbo and maybe other stuff once in a while.
I'm still thinking about chipping it, though, because folks are reporting better fuel mileage. At $2.xx a gallon a couple miles/gallon better looks REAL good.

I thought the stock turbo would only put out about 12lb boost? Using the Predator at either the high altitude or 60hp setting, I see about 18lb boost. With stock exhaust, it is not hard to get the EGTs to the bottom end of the red. I had a slight bend in the exhaust where a prior owner had backed into something, bending the tail pipe forward maybe an inch. I had that replaced and EGTs dropped about 100-150 deg.

When my truck was stock, it would pull 18psi boost. When I added my intake, exhaust, and chip, I could do 23-24. Then I added propane, and can go slightly over 30.

Are we talking different measurements here or different gauge calibrations? Atmospheric pressure is about 14.7 PSI at sea level. I'm assuming that lbs of boost is in addition to the 14.7 and I thought the stock ECU on the Fords would limit boost to about 26 total lbs of boost (including the 14.7) stock boost to about 12 lbs which is what my gauge reads stock at a 4k ft elevation. I'm more used to using BAR to measure boost as that is what my Audi uses. 1.8 bar is what the Audi does stock = about 11.7 + the 14.7 for a total of 25+ lbs of boost. I must be confused if my ISSPro boost gauge only reads 18 max on the 60hp setting and about 12 max stock.
The PCM, or ECU, will defuel once the boost exceeds 22psi. Because of that, I've installed a blow off valve to fool the MAP sensor into thinking I'm only hitting 16-18psi, though the engine is really making a lot more.
You're right. Atmospheric pressure is 14.7psi. Any measurable boost is in addition to that.
When you say your boost gauge is reading 4psi, are you at WOT under load? That's the best way to find out what your truck will do. Mine does 3.5psi boost at a 2000rpm cruise speed.

When I tow my 7k lb trailer, I see about 4-5 lbs of boost at 65mph on level ground. Max I see under WOT with the predator on either high altitude or 60hp is about 18 psi - maybe a short spike to 20 psi but that could just be gauge swing. 30 psi must be awesome!. I'll have to try your favorite hill in a month or so now that I have the predator installed <g> Last time, stock, I peaked around 70 as I recall about 1/rd the way up it.
