erratic idle and surge at very low speed

thermostats arent too bad. Im a chevy guy but after getting slaughtered with a 6.4 death wave that lasted the entire summer, i can say this... 6.0 is by far one of the easiest to work on. Nothing is easier than a chevy though... Everything is out in the open.
Could be a possible oil cooler being plugged that will cause the temp gauge to rise...

powerstroketech---amen to the ease of working on a chevy engine. I miss the simplicity but am learning a lot from wrenching on the 6.0 liter. I would hope I do not have a oil cooler going bad since mine was replaced 5 months ago. I've read all over the forums on the 6.4 banjos and upgraded fuel spring mod. Whats ur opinion on this? I'm not running a fuel gauge yet so I've been waiting on doing these mods. Necessary to monitor fuel pressure before doing this in your opinion? I just ordered a Powermax and coolant filter bypass so I need to wait a few weeks before setting up a full pillar of gauges. Currently using my Bullydog outlook to monitor egts and boost. Running SCT programmer.

Bill, you're comparing apples to oranges here, because you certainly can't be talking about a duramax! Those make 6.0's and even 6.4's look easy.

6.4 banjos and blue spring, do it anyways. It'd be NICE to know the before and after via a fuel pressure gauge, but doing it now without one certainly wont hurt anything by any means.

mdub, possible eric sent me extreme street tune, tuned for not having a functioning egr system? If so would this then cause the fan not to switch on? My concern on the fuel spring was having too high of fuel pressure and blowing o rings and such on a power tune which ramps up fuel pressure anyhow correct?

All of Erics tunes come with the EGR function turned off. Simply turning it off wouldn't do this though, the EGR needed to be plugged in regardless. Some people leave them in, even when they delete the cooler. The EGR valve would get no flow at all from the exhaust and would be turned off in tuning, but still physically on the truck. When you use tuning to shut it off, it can still physically be blown open though (if the cooler is still there obviously). The only cases I've heard of the fan not running are with a very specific strategy (I can't recall what right now), and the EGR valve completely removed. Some guys just took the EGR valve, plugged it in to the harness and zip tied it out of the way. You may want to ask Eric about this though, it could be as simple as a corrupt tune file.
Fuel pressure wont change with the tuning, and you certainly wont blow any o-rings with the blue spring. The blue spring is to counteract the new filters Ford sells, which are more restrictive and lower fuel pressure already. My guess is most people using new filters, with the old spring and hot tunes are already too low on fuel pressure. I run the blue spring and the old style, higher flowing fuel filters. I monitor my pressure like a hawk too. My diesel side only gets up to about 67psi at the highest. I have run my veggie side on 80+ before for many miles, no problems. I wouldn't worry about the spring or the banjos, just go ahead and do them.

When i pulled a couple turbos on the 6.7s i was amazed at the fact youd have to pull the cab to replace an injector what were they thinking.... so far theyre pretty bullet proof. The 450s and 550s ive only seen failed turbos and cracked up pipes. The transmissions are getting solenoids replaced under a new TSB. but other than 3 turbos this summer and up pipes ive yet to see any of the failures other techs talk about on FMCdealer.

The more gauges the better. Youll have to learn how to drive like a fighter pilot when your looking at gauges speedometer and the road itself but youll get used to it.

PowerstrokeTech- fuel spring and banjos will be going on next weekend for sure. Thanks for your input i value your opinion. I'm cool with all the gauges, Will run a quad pod on the A pillar, housing Boost, Pyro, Fuel pressure and oil pressure... would water temp be the next to add? Will also be running air pressure gauge for the air bags somewhere else...Anything missing? I was going to buy all these from Autometer in the Phantom II series or C2 series. I will feel considerably more comfortable with the gauges installed because I have very little confidence in the accuracy of the BullyDog outlook digital monitor I am currently running and from what i understand the ford factory gauge cluster is less than fantastic!
Powerstroke Tech- Last question for u; would switching the factory fuel pump on the frame rail be a good idea? Airdog or something of the liking? Mdub touched on this subject briefly on a different thread

I would get fuel pressure, engine coolant temp, engine oil temp, and pyro. Boost isn't really necessary, more of a "cool" thing than a helper. You can usually just hear if the turbo is working or not. Autometer makes some nice gauges.
You don't really know if you need to switch the fuel pump yet or not, because you don't know what your fuel pressure is doing now. It could be fine now, or it could be dropping under WOT on a hot tune. Get the gauge first, then see what you need to do to upgrade. An Airdog 2 would be what I would go with, since it's regulated at the pump, so not really a need for a full regulated return system.
