Hey guys, you don't need 2 Smarty's to compare 2 different programs. Just load one program up on the truck and then update your Smarty with the 2nd one. After a couple runs on program 1 you can update your ECM with the 2nd program.
I've done this a few times comparing 4.3 and 4.4, 4.2 and 4.4, and 4.4 and current Wild programming. My findings were that all versions produced about the same peak power, but not all at the same RPM's.
At the track I compared 4.4 and 4.2. Ran a 13.95 and 13.86 with 4.4 and a 13.95 with 4.2. To be fair, I did only launch the 4.2 at around 12psi when I normally launch at around 16psi. I still don't see an extra 4psi at launch bringing the time down any lower than 13.86 though, so IMO they performed almost exactly the same.
On the dyno I compared 4.4 and current Wild. Both programs made within 2 peak HP of each other, but 4.4 had an extra 105lbs of TQ. 4.4 also produced peak power about 400-500RPM earlier than the current Wild.
I also compared 4.3 and 4.4 on the dyno. Both programs produced almost identical numbers. Peak power was within 3hp of each other and occurred at exactly the same RPM.
The only real difference I notice between them all is that 4.4 has much more linear throttle sensitivity/positioning. I don't really think it's any less responsive, just smoother throughout the entire throttle range. With the current Wild and other Betas there doesn't seem to be any difference between 3/4 and full throttle. It's like all the power is crammed into the first 50% of the throttle positioning. I like to have more power left when I'm only halfway to the floor! $.02
