    Hptuners work with LH6 2006 Envoy Denali 5.3L?

    I am trying to tune out cat codes in a 2006 GMC envoy with an LH6 motor (I think) 5.3L. Wondering if I will have any issues if I purchase the credits for it to do this? She is just throwin a cat code that I need to work on

    Please let me know.

    Thanks!

    It says it's supported on the supported vehicle page.

    05-10 GM envoys with 5.3's.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.
