2021 Silverado/Sierra 5.3L/6.2L Support
The 2021 Silverado and Sierra 5.3/6.2L are supported on the latest version of VCM Suite
Beta software.
The E90 Exchange service will be required to tune these vehicles along with our MPVI2 and
10 credits for licensing. You will need to send us your original ECM and we will exchange it for
a HP Tuners modified one, giving you full access to calibrate, log and scan all via the OBD2 port.
Click here for our E90 ECM Exchange page for more details.
