Later model 5.3 or 6.0 injectors are a very common swap and they are cheap to buy online. The 5.3 flex fuel's are usually 37-38lb/hr if I remember right and the 6.0 injectors are 50lb/hr because they are flex fuel as well.

You can convert the GEN 4 data into GEN 3 format with ease using a spreadsheet. Input the data from the tune with the injectors you are using and it will convert the values for you.




You'll also want to copy over a stock 6.0 tune with the compare feature to give you a good base to start with. Find a 2006 stock 6.0 truck file and just copy over the entire engine section with the compare tool.

Thank you

Using the compare feature, do I need to do every table individually? Or is there a faster way?


Thanks for the helpful replies, I am doing a similar thing. In my case replacing a 6.0l with a 4.8l.
