    2015 LML Diesel Speed Limiter

    Have a friend who wanted his Speed limiter Removed. I removed it however he says his truck still cuts off at 103. Something I missed?

    I'm not sure how HPTuners is setup but for EFI Live I know I had a lot of issues until I found an OS that actually would work with me. There are several that if you remove the limiter it actually will kill cruise control and things like that. Don't know if that helps at all, Just thought I'd share.

    No there is nothing you missed. It's what your missing. Cant be done with hpt.

    I'd be scared of driveshafts going kaboom at those speeds if it's aluminum anyway.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.

    Well that sucks. Is it because of the Trans not being unlocked? Or just missing tables

    The only way I have been able to remove any speed limiters (LML has plenty of them) is to control the fuel limiters. I haven't found a way to do it with hpt.
