Not too sure on the specifics, but the f6 has the capability of being retuned with a computer by the User...so if you plan on doing your own refinement def the f6 is for you.


Also do not put your pyro in the down pipe.... or plan on the header. A friend of mine recommended to do it in the DP rather than one side of the headers since you will only be able to pick up that side from melting down rather than both sides. He has 3 puro in both headers and DP. He is also modded out to the moon with turbos and the entire nine yards. However I am considering to do a manifold Pyro too just for peace of mind. I have the DP set at 900 degree alarm.

I also found it very interesting that the economy tune on this truck ran cooler than the stock tune. Under the stock tune I can hit 900 a lot quicker than under the the economy mode. 140 tune I can get hot quick screwing around.

This being said I really do wonder what guys hit without a pyro under a stock tune pulling through the mountains around here. My boss has 300k on two trucks both with 12-15k behind them on average pulling around in the rockies. Has not replaced anything major besides a tranny. I am very cautious with this thing now, but am really interested in what these things stock heat up to considering mine runs hotter on a stock than with 80+ tune.

I have not towed with it yet but I can almost guarantee 1000-1200 on the pyro at the down pipe would come very easy heading up i70 with the race trailer behind it and the towing tune. However I'd like to bet another set of gauges it would get there even quicker with the stock setup....even though this is completely bass akwards of what I would have thought. It solely based off what I have seen on the guages.

I could be completely wrong, but no one has commented on my EGT question yet.

 

I have my pyro on the manifold drivers side. There is a nice flat spot to drill and tap. In 4th gear pulling a short hill with probably 1.5k lbs on the bed I hit 1000 on my pyro and couldn't get over 45 mph. I got something goin on but not sure what it is. I am goin to order the f-6 chip so in the future when I do other mods I don't have to pull the chip out and send it in. Can wait to plug this thing in. C'mon

 

What are you seeing for boost when you are seeing these EGT's? It sounds to me like you have a boost issue somewhere. That seems to me like it is awful hot with stock sticks and stock tunes.

That is more along the lines of what I would expect to see from a truck that has stock injectors and tunes. What are you seeing for boost numbers?

Of course this is all me just talking since I don't have anything to compare it to.....yet.

 

My max boost was 15 psi before the 140v IDM mod. Then I hit 17 psi once but very rarely. I got to hook up my DIY boost leak detector and see what's up. Just haven't had the time. Too much working lately!!! But I got play money now. Ha ha ha

 

That's how that usually goes you can have the play money or the play time, but rarely can you have them both! I think you may have a boost leak you're dealing with and that would definitely contribute to your higher EGT's.

 

A chip won't fix that issue as I'm sure you know.....thats a serious issue you should look into before worrying about the chip. 4th gear in a chipped 7.3 should be able to pull 12k over Eisenhower tunnel at 65.... been there





ANYONE WANT TO ANSWER MY EGT QUESTIONS?????

 

I am going to be quiet on this one as I don't tow much and don't have gauges in the truck yet....

 

I do not have a boost gauge.... was not sure sure why it would be with stock injectors and a minor tune. I'm guessing I'm going to be picking up a second PYRO and boost gauge and bump up to 3 gauges..... sooner than later. The turbo seems fine and spools a lot smoother than either of my bosses truck I drive. The turbo on this truck appears to be in excellent condition.... I would like to be doing an intercooler here soon if its worth the cost.


My buddy melted down the right bank of his motor after a snapped injector when having a pyro only in his driver manifold and that's why he suggested running a DP mounted PYRO. He now runs one in driver, passenger, and DP. His alarm is what usually sets off at 900 on the DP pyro well before his Driver side pyro makes it to 1250.... Like I said before he is running a heavily modded truck compared to a simple intake/ chip/ exhaust. Thought I would be safe with a single one at 900 on the DP. As aforementioned I figure most Tractor Trailers locate theirs there as well so it would be a good idea to stick to it.... I'm learning a lot lets just say.

I read the thread about manifold vs DP as well after the install. I DO NOT want to abuse the motor and did the chip simply for a bit more economy and strength, as well as towing.



I take my truck to a good friend and Ford Factory trained mechanic who runs his own shop.... I trust his judgement on these matters since he works on diesels day in and day out. His 6.0 has had a chip on it since day one and he has not had any issues yet.

 

When I had stock injectors and my chip I couldn't make my truck get over 1100* empty or towing

 

That does make me feel better however I have seen a lot of guys sitting on the side of the highway near vail and Eisenhower with super high readings when towing heavy loads over. A lot of people that do bring their fifth wheels over the summer from non mountainous states, to the rockies are very surprised how hot they get their trucks over some of the passes. There are a few thready on here about it. I70/Monarch/and quite a few more over the divide will get any truck/tractor pretty hot

 

It you have your EGT probe in the dp and your seeing 1100-1200* then it's way hotter then that. The exhaust in the DP is 300-500 cooler in the dp then it is in the manifold

 

I just hope my up pipes aren't leaking. And again haven't had time to be a contortionist and get in there to really look but everywhere else shows no sign of soot. Where are most boost leaks found?

 

I agree the highest I have seen is 850 at the DP but I have not been towing yet. I will lay off any where around 900-950.... Like I said I can hit 800 with a stock setting getting on the high way, not any cooler than the 80 econo tune doing the same. Hoping an intercooler next month will help out a little bit. Any one running water injection? kits are only like 600 bucks.... any negatives? I was planning to run this as well on the blown 466 efi I'm building for the other truck.....

Up pipes or boots.....

 

Build a leak tester. Leaks can be found at the uppipes, turbo flange gasket, boots,intake plenums, and where the turbo and spyder mate

 

My boost builds really slow and finally builds to 15 psi with WOT @ 2500 rpm. I pretty sure I have leaks. I think I am goin to get that quick spool turbo housing from riffraff before the chip and after I check for leaks. My little 3 gallon compressor wouldn't build any pressure in my system. I put a pressure gauge on the cap and it don't even move the needle but the rubber expands on the cold intake side of turbo. I think I need a bigger compressor.
