Tuning an 0411 Swapped 454 Big Block GMT400

Last time I showed you guys the wiring process of converting this 1999 K2500 Big Block Truck from the black box PCM to the more powerful 0411 LS1 style ECM. This will have many benefits in the long term, from optional 3 bar speed density, a higher RPM limit, and a whole lot more. This process starts with a 2002 Chevy Express operating system and L31 calibration, which has to be tweaked a little to work with the 454 L29. I use HP Tuners software to do this, but the beauty of the 0411 swap is you can also use EFI Live as well.
