    Depends on whether you wanted to optimize for lugging around, all out towing power or all out power period... Even when surging hard the 38R makes excellent power and isn't really that loud. It's nothing like a stock turbo chirping and dropping boost and crap. The 38R still does the job of...

    Tuning 101 - Thread Merged with Injector Posts

    I don't have a boost gauge and didn't have the PCS monitor up. Somewhere in this thread I listed boost per rpm previously. It's a little better now, or at least it makes a bit more power per pound of boost because I had to up my trans line a bit at power levels below full power and my trans...

    Well, I took some time to fine tune the program during the hotter weather and to dial in the pw and icp for towing and low rpm lugability with great results. The truck will confidently lug down near 1000rpm while driving around and still have sufficient available power to pull up most hills...

    Just don't make a bunch of changes to a base file on your desk and then think you've concocted the perfect file. Make sure you start with a base file and make a change at a time once you get in the truck so you see what does what. A lot of it will be counter-intuitive or sometimes flat...

    Don't know EGT, I don't have a gauge... this truck has no gauges aside from the factory cluster. Watching boost on the PCS monitor, the truck is making 5 to 10lbs of boost. If it were getting too hot I would smell/feel it. With no visible smoke, it shouldn't be hot anyway. It's got an old...

    I took a minute to dial my 02 Manual program for the hotter weather and really made some big strides. I had the truck pulling hard at 1200 or so rpm with a dual tandem gooseneck in tow at 3000psi with very little visible exhaust. That's tough.... with any injector nozzle. The truck would...

    Yes, you can use whatever sensor you want. The PCM analog to digital converter only sees voltage, doesn't care what the pressure range is. Problem is, it will control MFD, not just pw, so you lose icp AND pw instead of just pw... I don't want to lose ICP at low boost. I need all my icp to...

    Even if it didn't, you can't add programs.... so if you selected to burn a 2 position to burn the two files you wanted to add, it would burn the new files into slots 1 and 2, not 5 and 6.....

    I can't remember if it formats the entire chip when you burn it or not... Regardless, the one you have would be programmed in positions 1, 2, 3 and 4, so even if you wanted to add to and it did NOT format, you can't select to burn to 4, and 5.

    Tuning is tuning. Things get harder the faster the injector, that's about it. Conceptually, everything is always the same. When to spray, how hard to spray, how long to spray. There is NOTHING else going on with 7.3 diesel engine tuning... all the maps, parameters and functions in the...

    Possible cracked block?

    1500 degrees means nothing unless it's sustained. 2000, then you would need concern. Looking at your pistons..... you NEVER saw any decent heat. Period. They would have at least 2 or 3 cracks coming out of the bowls, and they don't. I've never had an engine apart that did any towing with...

    May have destroyed my locker

    Pattern would be unchanged, he didn't move the pinion. But backlash would have been good to know, lol.

    May have destroyed my locker

    I've had a truetrac in two superduty's now and it is the best street carrier on earth IMO. Just goes. Hardly ever opens under power. A word of caution though, I broke some kind of snap ring on my first one, although it never stopped working, and it's still in the truck to this day about a...

    Headlight foot dimmer switch again...

    I can't imagine that it could take more than a couple hours. I don't have a lot of time and this is low on my list. This thread wasn't mean as a "hey, look what I'm doing" but a question for info to anyone already having done it. Whenever I get around to it I'll describe what I used to do the...

    NO dumbass... Just make any fuking right hand turn and meet a car. Done. You now have to take your hand off the wheel to dim your lights because your left hand is at ~3:00 on the wheel... and the plastic pos stalk is at ~9:00... How fuking stupid do you have to fuking be to comprehend...

    You're in the middle of a sharp right-hand turn and here comes an approaching car, lol. As for the radio, my left hand stays on the wheel at all times.... right hand does EVERYTHING else because it's on the RIGHT side of the wheel. Radio, heat, cool, defrost, vent, gearstick, trailer brakes...

    Steed Speed 7.3 manifolds

    Do you have a picture of the setup? The problem is not the material, nor the strength of the material. A stainless header will see your aluminum pistons in the bottom of hell before failure if designed correctly. I wonder what the environment in a top fuel header is like for instance. We are...

    Steed Speed 7.3 manifolds

    Then headers it is. I would wager a lot of money that your last failure was due to lack of expansion/contraction allowance. Things like to grow when hot. It has to go somewhere. Stainless likes to grow a LOT. Do you have a picture of your cracked up setup? It's usually instantly obvious...

    Steed Speed 7.3 manifolds

    As you know, the point of the header is to isolate each pulse to promote scavenging by the exhaust gas and deter reversion by keeping adjacent cylinders pulses away from each other until an optimum distance is found where the inertia of the flowing pulse can balance the ability to clean it's own...
