What you chose to tune and data log with is up to you. This forum is for those that are willing to put up with a little less user friendliness, not all vehicle OS supported but cost less to use...

And on the running rich, remember it is in open loop with your open exhaust and no O2s. If you are going by exhaust smell you really don't know what it is. With the amount of overlap that cam has and...

Here is your bin file with 8.1L MARINE injector data in it.

First of all you absolutely can not run open exhaust with a closed loop fuel system and O2 sensors. Even with correct injector data it will flood the cylinders with fuel when it goes into closed...

You have a 05 Silverado AWD LQ9 6.0L VIN in a 04 6.0L LQ4 OS but you said it is a swap vehicle so not sure what you have. What fuel rail and fuel system do you have? Does it have a vacuum referenced...
