0411 l29 454 vortec swap

[bigtoyota69]

hi everyone

im wanting to do a 0411 swap on my 99 k3500 with 454 i already have a pin out to do the swap. im just lacking and cant find much for the 0411 454 swap.
basically trying to find a base tune so the truck will run then go from there or if someone has a tune set up for towing on the 0411 454 this would push me to the right direction for sure. if anyone can help or point me to the right direction i would greatly appreciate it.

thank you everyone

I have not started this project , just bought an l29 truck yesterday. You would basically have to pull up a bin file with all of the 454 data and compare that to the one on the 0411. You could use 2 laptops, maybe 2 hours of changing and checking settings. Find the pinout on the blackbox that you have. Would be better if there were a tuning software that has a compare feature that works like this but the configuration of the xdf files would be way off and be less efficient. Once you get her to fire up post your base tune up and there you go.
