I’ve done segment swaps before but I don’t have a 4l80e segment with the correct OS to swap in. I emailed HP Tuners and they said that I need to change the OS. Any idea how I do that?

So as the title states, I have a 1999 Silverado with a 5.3 that I just did a 4l80e swap on. It has a 9373372 OS and with the tune repository gone I cant find a tune that I can segment swap. Could...

no the car was pulling hard and running like a champ. then I checked the scan and was like :bigshock:

my first guess was that the maf was shot. no dude i know ur not tryin to be a dick. I was putting on the same basic tune that i ran just fine on my car and instantly his was showing 11* KR

we put the stock tune back on the car and it was still showing 11*kr at idle
Think hes gonna take it to the dealership.

So with the new beta version tuning an LNF there is the option to change the Boost control under torqe managment/turbocharger. With this do you still need to change the DAL under airflow? do you...
