The wait is over! CCS tuning can now unlock the true potential of your 3.0L LM2 Duramax. Unlike most tune files on the market, CCS offers true custom tuning for your 3.0L. You just have to let us know what your upgrades and preferences are, and then we will have the tunes written to accommodate any modifications your truck may have.

We do not support lope tunes or smoke tunes.

This tune file is compatible with the HP Tuners MPVI2, MPVI3 & MPVI4 devices.
