EFI LIVE : DTC codes before installUpdated 9 months ago

We strongly recommend that customers install our delete tunes only when there are no DTC codes present. This ensures a clean slate for the installation process and helps to prevent errors. While our tuners are able to clear emission-related codes, including permanent ones, it's still best practice to clear all codes possible before installing the tune.

If you have only emission-related codes present, it should not be an issue. However, if there are other codes present, they must be removed/cleared before installing the tunes. If you are unsure how to clear the codes or need assistance, we recommend taking your truck to a professional diesel mechanic who can help you clear them before installing the tunes.

Please note that our tuner will clear any emission-related codes, but we still recommend clearing them before installing the tunes. We want to ensure the best possible outcome for your truck and installation process
