I installed an Edge Evolution mainly for the gauge features. I also installed a B&D exhaust brake and a 4" cat back exhaust.

I wanted to get a good baseline of engine temps in stock mode before really towing anything in the econmy or tow mode. (I'll never run Extreme mode)

I tow some pretty heavy stuff. So I'm often close to maxed out as far as the rating of trucks tow rating.

Saturday I pulled my horse trailer up and over Trappers Loop. It's a 7-8% grade. 4-5 miles up hill and 4-5 miles downgrade. In the past, I used to just keep the pedal to metal to maintain speed up the grade. My truck pulls my trailer over that grade about 45 mph. With the new EGT gauge I could see my temps were pretty consistently in the high 1360-1370's. I always kinda figured my stock ford programing wouldn't let me over heat the EGT. Engine was running around 2800-3000 rpm, 22psi boost and 45 or so mph.

I've always been told not to exceed 1350*. And to try to stay below 1250*. What temps do otehrs see with their stock programing. I'm scared to think what temps I was getting prior to adding the Evolution and exhaust.

On another note, my BD Exhaust brake does a good job of holding back the load on the down hill side of that grade. Prior to adding it, I was riding my brake a lot going down this same grade. With the exhaust brake I can just walk down the grade at 40-45 mph and hardly touch the brakes.

 

Painted Horse,

1350 is pretty much a max number towing, and running 1200 or below would be better. Remember it is not just the EGT's going up, you are also running increased Water & Oil temps. High engine oil temps (above 260F) can cause serious engine problems long before the high EGT's ever effect the turbo.

The factory Ford programming generally backs off the fuel when the Water temp or Engine Oil temp gets to high, but ignore high EGT's. IIRC you have to get the EOT above 260F before it starts to defuel. This is too little to late IMO and the reason i feel A/M gauges are mandetory for anyone who tows.

 

This is why I bought the evolution. Was for the gauge feature not the programing. I know I'm real close to the max weight my truck is rated at, And I just suprised to see the factory programing really hit that high of EGT temps.

But at least now I can take my foot out of it when I see the temp exceed 1300.

 

I am glad to see you are happy with the BD Exhaust Brake, they really do work well.

My reason for posting is your boost numbers though, I think you may be making more than 22PSI boost and you should be. I am stating to think that 22PSI of boost is all the EVO gauge will display although the truck is making more. I have been working with a few customers regarding this issue and have not been getting a lot of help from Edge on this theory. Does anyone else have any feedback on this.

It seems strange that NO ONE is seeing more than 22PSI boost with EVO, that's the wall although the truck should be making more? I have seen 6.0L's making 30 PSI boost with a BD X-Tuner and an analog boost gauge. Could it be that Edge is restricted the boost to 22PSI to prevent head gasket issues common on the Ford 6.0L??? to many questions, not enough answers LOL

I truly think because the EVO is going through the computer it can not display the true boost numbers.

 

I have the MSD Dashhawk, which is pretty much the exact same unit as the Edge Evolution (MSD owns Edge now). On my Dashhawk I can get up to 28psi of boost with the factory programming. This matches the readings of my Ford in dash gauge.

Is 22psi his max reading, or is that just what he is reading as he is pulling the trailer up the hill? The only time I see 28 psi is under hard acceleration, not just driving around, even uphill.

 

Thanks for the feedback, what makes me think that 22PSI is all it displays it because so many people are saying 22PSI, not 21 or 23, its like 22 is the wall. I have had some guys say they get 22PSI right away and it just stops there??

I have sent out a BD boost fooler kit to a member on a different thread and when he installed it he still only got 22PSI on the display but set the high boost check engine light that tells me he is making more than 22PSI???

Perhaps we can have some of you disconnect the waste gate and see what happens... does the display still read 22PSI but set a high boost code?

 

Painted horse, what kind of weight are you towing?? I am interested as I am possibly going to exceed the weight rating when I start towing, and I have the same truck as you.

 

I towed about 6K out West, through SD in 110* and never saw over 900 maybe 925 on mine. HTH

Tranny temp spiked to 220 until I slowed down a little, water temp never went over 220 either, fan seemed to do just fine cooling it down. Going into a pretty good headwind too.

 

Dave, there is no wastegate on the 6.0L.

If these guys with the Edge Evolution are seeing a max of 22psi boost, it could be something in the programming. I believe they are able to limit boost in the programming in order to avoid lifting the heads and blowing headgaskets. Matt and Jody at DP Tuner would know more about that than I do though. Jody actually writes his own tunes for the Evolution so he is probably a good person to contact about that if Edge isn't responding to you.

 

oops getting my 7.3L and 6.0L threads mixed up, sorry if I confused anyone!
