Well I loaded up the HP and was really impressed! In the city that is just too much power to play with although drives great at partial throttle. Floor it for 2 seconds and I'm over the speed limit. I'll take her on the freeway tonight and see how she does.
My truck is hooking up well and I think I'll save the HP for the track after I let my dad drive it.
That much power just feels like it is going to tare something apart.
Unfortunately my EGR got disconnected and max boost I am seeing is approx 26lbs which is what it had before untuned and EGR plugged in...is this normal?
The tune does seem to make the trans run hotter but my EGTs stayed close to stock. Then again I've only had the "Tuned 6.0 Grin" for 36 hours.
Nice job Vic and thanks for all the FTE boys for helping me make a sound, informed decision.

I frequently see 26 psi driving around town with the odd bit of stomping on it. Max boosts of around 32 happen for me when I've had my foot in running up the test grade near my house. Did catch a 34 psi once on the X-Monitor but that was a fluke I think.

SCMT problem
First, I am not bashing the SCMT, I truly do hope I can get it to work well on my truck, but here is my problem. I sent my 1704 off to be updated for the new ford flash, got it back today, and I must say that I am disappointed. I put on the high performance tune, and now the truck (late 03 build 04 with torque shift, turbo back 4" exhaust with stock cat and X-monitor gauges) will run up to 4k RPM, and then defuel considerably before hitting the next gear. Uphill, it will not shift at all unless you let off. I really don’t like the idea of my engine running up to 4k, especially since it makes so much power below that high of an RPM. I drove the truck for about an hour on some back roads running the truck moderately hard for about an hour, ran though all of the gears (including reverse) hoping that the trany just had to learn the new tables, but it never got better. Then on cruse at 50 mph up about an 6* grade, the turbo compressor started to surge somewhat violently, with by boost jumping up to 26 psia, which I know is not excessive for a full power run, but is for about 25% throttle. This has not happened while stock, so it leads me to believe that the tuner changed control for the turbine blades, causing an over boost for the low throttle setting, which then with the engine not needing that much air, caused the surging. <O
</OI have not had a chance to try the other settings on it yet. Is there someway I can have the trany shift at a lower RPM, or should I send the tuner back? I only ran the tuner on econ setting before the flash, because I did not have my EGT and boost gauge installed yet, and it seemed to run fine in that mode. I was really looking forward to running the SCMT, but with the horrible shifting, the truck is slower than stock, and much harder on the engine, not to mention the compressor surging. Thanks for you advice DeesO<O

</ODeesO,
All you have to do is read the overwhelming number of pages on this thread to realize that something is definitely NOT right with your setup. If you haven't tried it already I'd suggest you reload the stock tune to the truck, make sure it operates "normally" again, and then try reloading the performance tune.
As a former computer consultant I can tell you that it's not beyond the realm of possiblity that the "tune" simply didn't load properly, and the computer is now "confused." Superchips may have protections against allowing a faulty tune to be loaded, but even so it makes sense to put the computer back to stock and try again. I wouldn't be at all surprised if it works better the second time around.
If you still have trouble, be sure to give Superchips a call and let them know directly what's happening. There's a good chance they will be able to correct the problem and get your truck "haulin hay" the way it should! Oh, and by the way, when it's working right you get a very strong pull all the way to that 3900rpm shift point, so it starts to make sense why it's set so high. And there's no beating the sound it makes when it's running right at WOT (wide open throttle)!! It stops sounding like a diesel and starts sounding like a "massaged" conventional V-8, at least from inside the truck!!
Good Luck!
Steve

I will try to reload it, I was not really in a situation where I could sit there at reload it today then test it again. I remember reading somewhere on here that it sometimes takes a little while for the computer to adjust to the new setting, and I was hoping that this was just the case here. I will update what happens tomorrow

So today I put it back to stock, and it ran just like before the tuner was put on. Put the HP tune on, and it still had the shift issue. I then put the econ tune on, and it ran fine, except that it would lightly surge at WOT in the upper limits of 4th gear (3200 RPM) with a frequency of about 4 small surges per second (felt like a gasser with two sequential plug wires off). On the way back from the test drive, I put the HP tune back on, and it then ran fine in the HP with the shift points at 3900 at WOT, and no defueling. One thing that I did notice was that a couple of times the trans seem to slip up shifting at about 70%t throttle, with about a 150 RPM jump for about a second before hitting the next gear, and it seemed to do it less with time, so maybe the computer is just getting used to the tune. I have not tried to duplicate the condition where it had the hard surging, but it did not give any indication that it wanted to. I have to say the truck runs like no other now; I’m hoping the little shift issue works itself out so I can start harassing the GTs again.

ICP varies with tunes?
Just curious on something. I've been switching back and forth between Tow-safe and Economy - my truck appears to be slightly quieter with the tow-safe tune. Do the higher power tunes by chance use increased Injection Control Pressure? Anyone notice similar?

I could be wrong, but I don't see SC messing with the Idle ICP in any way. I'm not quite sure what would cause a difference in idle noise with the SCMT, other than possible EGR manipulation (but I really don't see that happening either).
SC doesn't use tremendous ICP at any throttle position. If you want to hear racket, rescale your ICP for a higher pressure max than the pump can actually provide, and set the WOT IPR duty cycle at 100%

Wow ... just goes to show how different two supposedly identical setups can be. My '05 Excursion (Really an '04 in disguise ... Aug-04 build) is hypothetically identical to your 05, and yet the noise at idle is significantly less in stock tune for me.
Of course in any big diesel we're not going to be sneaking around many neighborhoods un-noticed!
