You need to control the transmission so Dynamic EFI/EBL is out unless you want to bastardize together a dual PCM setup.

I personally wouldn't recommend TBIChips.

Dave W is amazing here and tries to selflessly answer any questions he can without mentioning that he could just do the tuning, but he could help with it if you do care to employ him.

Best results would occur if you were willing to have a laptop and get the PCM setup with the hardware to do emulation. The logging and modified bins can happen fairly quickly, much better than mailing chips. Depending on the circumstances, it's even possible for someone to remotely take over the PC and work it directly - even while driving if you can get 4G internet in the truck (a hotspot phone).
