Does the Edge Evolution firm up shift points?
I'm in the process of comparing the Predator to the Edge Evolution tuner. My principle application of the truck is to tow a gooseneck horse trailer.
The predator literature indicates it has 3 transmission adjustments (none, firm, hard). The Edge Evolution never mentions any function to control the shift points.
Does anyone know if the Edge controls the transmission?
Does anyone have good/bad experience in using a tuner to firm up shift points in towing applications.
The vendor I spoke with indicated that the Predator may not be optimal for my truck ('99 PSD) given the upgraded programming it uses against an older truck. I didn't get the feeling he was trying to sell me on one or the other as they carry both.
And yes, I have guages, kwik air mod, and 4" downpipe/exhaust.

The Edge doc's make no mention of modifying the transmission. In my OBS, it had no effect at all. I've added the Banks TransCommand & SmartLock controllers to, among other things, firm up the shift & control T/C lockup (which it did).

When you say upgraded programming for an older truck?? what exactly do you mean by that?? I have the predator, and have tried the superchips tuner, as well as the edge. I have been around diablosport for years, and have had several custom tunes burned for various mustangs, and think they are about #1 in my book for tuning. The predator has 3 shift settings, but on WOT on the auto pickup we tried it on the shifts weren't crisp and hard, to prevent damage on the tranny I'm guessing. BUT it was alot firmer than stock. After letting Lariatbob try my predator around the block, he ordered one, and a few friends of mine have sold there used hypertechs to buy predators.

Regarding programming . . . the retailer mentioned that the Predator is optimized for the later model 7.3 PSD and had heard of some folks saying it wasn't as good on older models. Just what he said, I didn't interpret it much.
The research I'm doing right now is finding the distinct differences between the Predator and Edge. Both have multiple programs, are code readers/resetters, etc. Then I noticed the Predator has a transmission program where the Edge does not.
So now my research is telling me the Predator can do everything the Edge can do and more. So I'm wondering why anyone would buy the Edge over the Predator other than a small price difference?
Given I am towing I feel I could benefit from tightening the tranny to avoid any potential gear hunting on long climbs.

Firming up, or "tightening", the tranny won't help avoid gear hunting at all; it will only reduce the amount of time it takes to complete a shift. Not that that's a bad thing; less shift time will increase the life of the clutch packs. The presence of more power will help reduce hunting, but proper gear selection before the climb is most economical. Kick the trans out of overdrive just at the start of the climb to avoid WOT and the associated fuel consumption.

I ran my buddies Edge EVO out of his excursion - its an older Edge Unit - that as Ive been told - needs a firmware upgrade. Part of the tuners firmware upgrade, has been to alter the tranny line pressure and shift points in the Extreme and Tow modes. The older software was a bit too hard on the trans - so Ive been told they toned it down
What exactly the Edge does with the trans and shifting is a bit of a mysterious BLACK BOX still to me. I had planned on picking up one - if this Diablo Predator Unit I got for free didnt work [It didnt - the tune is in another truck, and I cant get it reset] Id planned on doing a little Q&A with the Edge folk to get trans info.

The Edge raises line pressure a bit and modifys the shift points. I'd reccomend installing a Sonnax kit as well.

The Edge Juice with attitude combo does defuel at a certain EGT set point, but that combination offers no transmission shifting improvements and the HP gains are lower than most offerings out there (70HP).
If you want defueling when your EGT's get high, you may consider a Bullydog Outlook monitor.

They will defuel with most any chip at a certain set point.
Let me know if you have any other questions, I am a Bullydog dealer and can hook you up.

The Edge Evo does indeed play with line pressures and shift points, but they are not end user adjustable as with the Predator.
However, if you have an Evo and wish to do away with the trans programming, you can send it to Edge and they will remove the trans programming.

By "later model" PSDs, the retailer meant 99+. These all had the intercooler and split-shot injectors. According to the info I have, the Predator works better with the 99+ than with the pre-99 OBS powerstrokes.

Yes, the Edge Evo does change the way the trans shifts, depending on which program you select. I have an Edge Evo made in 11-04, and on my 96 E350 I hated the way the Race (midlevel) program made the transmission shift.
There was a HUGE difference in power, but it raised the OD shift point by about 7 mph, and made it shift much more firmly. I didn't like the high rpm shift point with this selection, and I didn't like the jerk when it shifted. Basically, I didn't like it that it wouldn't shift to OD at about 42-44 mph anymore, and I found myself trying to make the shift smoother by letting up on the accelerator right when it shifted.
The Tow (lowest setting) has the stock shift points, but I can't really tell any difference on this truck in power when compared to stock. I think I will go back to stock, and sell the Evo. Anyone want a good, like new unit?

My truck was manufactured in 8/98 so I don't know if this classifies me as an "early model" 99 or a 99+. I am assuming I am a 99; in which case then maybe there is some truth to how well the Predator works with this year. My vendor said he knows the Edge works well with my year but believes some folks have had trouble with the Predators on this model year.
99 seems to be one of those years where ford made a few more "adjustments" than normal to the F-260/350 PSD line. I'll post a separate thread for those that are interested to discuss the known differences of this particular model year.
