Delete with emissions EFI tune

[Neil57]

Have Idaho Robs emissions compliant EFI tune on my 2009 lmm, thinking of deleting, will the tune work if I select the off road selection and reload over the original? Are all his tunes double duty or is there only one tune on the Autocal? Thanks

I would ask ATP....

Knowing Rob, I highly doubt it, but like Rick said, call them directly.
