You need to exchange your ECM (or a spare one) for one that is enabled for tuning with VCM Suite. Then you use VCM Suite 4.1 with MPVI2 to tune normally via OBD2 port.

Did you have any luck with getting yours tuned?
I've had a few people tell me different meanings of hp on the selections after I tuned a L5P 22 gmc. One said 1 is stock and goes up from there the other said 0 then goes up from there. I have 0-5 selections. Just wanting to get some clarification on what hp is in each selection.

If i'm not mistaken the program looks at zero as the number one switch position/ stock . Program has 0,1,2,3,and 4. if you have a switch its 1,2,3,4,and 5
