Are the motors mechanically different? Is there a different computer in the stronger '03's? Can the appropriate parts be purchased for an '04 that would allow it to run the '03 strategy? I'm sure I'm not the only one who would be fascinated to know the answer to "Why can't it be flashed?"
Of course, the follow-up question I asked is valid too ... at the end of the day, is there a noticeable difference in power when using the SCMT?

In all seriousness, some subjects are held proprietary and our findings here are one of them. I can't share much other than the fact that they are "different".
A tuned 03 is in fact stronger than a tuned 04.
You could put me in either truck blindfolded, and (if I could drive it without hitting anything) I can tell the difference between an 03 and an 04 immediately.
Aside from the power differences, there are signifigant differences in drivability that may feel subtle to some, but I find them really obvious.
The 04's have a bit more lag out of the hole, but have a crisper throttle feel in general. I've tuned both strategies as optimally as I can, so they all drive really well when tuned, but you can still feel the difference.
The 03s also smoke more than the 04's (tuned)

This is only at part throttle....it still rips at and near WOT =o)

Exactly, this shifting program is the best I have experienced......period!

39.5" tires will work fine.
However: (and this is a big however)
I STRONGLY recommend you changing out your rear axle gear, whether your truck is stock or tuned.
39.5" tires raise effective gearing (in other words, it makes a similar result to a numerically lower rear axle ratio).
This increases load on the engine and trans (especially when running on a turbocharged vehicle). Boost is load dependent, and you will often see higher spikes with this combination. This doesn't mean the truck will be faster...in fact it will probably not accelerate as quickly because the effective gearing at the tire has been changed.
39.5" tires should have an appropriate gear swap to keep the proper effective gear ratio at the tire.
For example, if you truck came with 3.73's and you change from a 31" tire to a 39.5" tire, you may need 4.56 or even 5.14 gears to maintain the same effective gearing and avoid excessive load on the engine and trans under acceleration.
Failure to install the correct gears will result in greater load (especially when towing), higher EGT's and a faster rising EGT.
This can cause problems in stock or tuned trucks.
Many a Dodge truck and Ford 7.3 p-stroke have lost a tranny due to the ill combination of big tires and a stock gear.
Basically, if you can dish out the cash for the tires and rims, make sure you have new gears to go with them.
A 33" tire would be one thing, but once you surpass 36" you should look at a lower (numerically higher) axle ratio.

HP and Torque curves for all tunes
Vic,
I've just ordered my tuner, and based upon my reading, will go primarily with the Economy tune. What would be interesting I think are HP and Torque curves for the 3 tunes. One chart showing HP for a stock vehicle and the three tunes, and another showing the same for torque. I understand the aspects of when to use each tune based upon my towing needs, but it would also be beneficial to be able to pick your tune based upon your driving style and where you'd like your power. Anything like this possible?
Tks,
Mark

Production date was Nov 3, 2003 (Engine: Oct 30). I had it flashed to the second update for '04's back in July. Its running well with that version.
Also, I've installed a Banks cat-back to help keeps things cool.
