EFI Live issue

[dalejr052001]

i got an 04 LB7 six speed duramax with EFI live on...when i go to speed shift the truck will rev out...it does when you go over 3000 rpm and try to shift...any suggestions to what it might be

Who built the tune?

danville performance...not exactly sure what five tunes is on the truck

It's not an EFI Live issue, it's a trans or tuning issue.

do you think having the efi live re-flashed with a different tune would help???
