Downgrade Do90066.05 for CSP tune okay?

[undergroundak]

I have an 18' DO90066.05 PCM. The closest tune file I can find is DO90066.03 that can be converted to a CSP tune. Quick verification that going back to the .03 rev is okay?

Thanks!

You'll be fine. I use that same .03 file for all my 68rfe 18's

Perfect, thanks!
