Get Your 2019-2021 Silverado/Sierra Ready for Tuning

HP Tuners offers three options to get your 2019-2021 E90 ECM-equipped vehicle ready for tuning—Purchase, Exchange, and Upgrade.

E90 ECM Purchase

Purchase a brand new E90 ECM for your 2019-2021 Silverado/Sierra 5.3L / 6.2L truck that is already upgraded for tuning. This is ideal if you need your vehicle up and running as quickly as possible.

  • E90 ECM Purchase: $699.99 (receive brand new, already upgraded E90 ECM) (no core needed)
  • ECM (E90) License: Purchase (8) Universal Credits to license your ECM.

E90 ECM Exchange

Send us your original ECM and we will exchange it for an HP Tuners-modified one, giving you full access to calibrate, log, and scan all via the OBDII port with your MPVI2 or newer generation interface and the latest version of VCM Suite.

  • ECM Exchange Service: $449.99 (send in a core, receive a modified core back)
  • ECM (E90) License: Purchase (8) Universal Credits to license your ECM.

E90 ECM Upgrade

You can now upgrade your original E90 ECM by sending it to HP Tuners. We will upgrade your original ECM so it’s ready to accept tunes, and then we’ll send it back. After upgrading, you’ll have full access to calibrate, log, and scan via the OBDII port with your MPVI2 or newer generation interface and the latest version of VCM Suite. This option does not require an IMMO relearn, crank relearn, or “Replace ECM” function as long as the ECM is installed back into the same vehicle it came from.

  • ECM Upgrade Service: $449.99 (send in your original ECM, receive your original & modified ECM back)
  • ECM (E90) License: Purchase (8) Universal Credits to license your ECM.

Credits are not included in any control module service.

No IMMO relearn, crank relearn, or “Replace ECM” function is necessary (as long as the ECM is installed back into the same vehicle it came from).
