Rev Limiter issue

[SCalla0490]

Hey guys. Buddy has a GT350, PMAS intake, Lund tune and e85. Having a weird intermittent rev limiter issue. Lund confirmed the limiter is set to 8500rpm. But when winding it out, hitting a limiter even before 8000rpm (confirmed by Brandon at Lund also)

Said it could be possibly a my key issue..... Can anyone help me out with that? I know theres videos, but how would I clear the my key?

Thanks!

I would question if it's really all "adjusted in the tune." It sounds like the factory nanny is kicking in then on a car that isn't warmed up.

It sounds like the factory nanny is kicking in then on a car that isn't warmed up.

Our manual clearly states that but I’ve never seen discussions on this. What exactly does this mean? X temp will get you X RPM max, the higher the temp, the higher RPM max? I’m sure there is a sliding scale that’s linked to oil temps.
I’ve never tried to go full send unless the oil is 190F+.

Sounds like it's hitting some other value limitation that's not met yet, like others mentioned could be oil temp or something similar.

Is this issue occur when the car is fully warmed up?

Figured I’d update for anyone else who has a weird issue like this. Brandon at Lund figured it out. Was getting a code for P1888 and P188E which was a diff temp short circuit. He disabled/adjusted that and problem fixed.
