Whether that be "X" programmer's way of writing files to flash ECM, or their way of tuning, or it may be exactly the missing link to torque management, I can't say because it's hard to decode the HEX format into something that's understandable. I can tell you having the torque tables opened up with what you're trying to do DOES make a difference.
Now, trying to tune around it without cheating with a box tuners base file? You can, somewhat. But it kinda negated the whole principle of getting the truck to run how I wanted it to on the streets and all around. Until we have some type of better control over torque management alone, it's kinda of a tradeoff.
Oh, FYI, it took me several phone calls and 3 OS's to finally get my tuning to take effect like it should. I.e. Pulse limiting option had no effect (always limited no matter what setting) with other tables even using files that the box tuner didn't touch. I'd copy, script, update you name it from the base tuner file into a fresh untouched file, and it'd run like crap. Partly due to some files were nit being copied or written right, and partly due to tuning with tables that I couldn't see had dramatic effect on the tuning with it. Im just trying to save somebody else running into the problems I did. But we're all big boys. I won't EVER try to cheat again! What I've got now is good enough, better than everything I've had before, but with torque tables supported via EFI, I really don't see anything else to be had.
