I'm doing a 4l80 swap to my 2005 1500 Sierra , can I do a custom operation system after doing the segment swap for my stock tune.
My setup is as follow :
418 ls1
Custom intake
Twinturbo
3bar map sensor
#80 injectors
Cusome fuel system with surge tank

I'm planing to run 2 bar of boost.



Thanks in advance
