Ive got a 2001 F250 Superduty 5.4 im looking at a tuner. Has anyone used the livewire TS with their 01 superduty? they seem like they might be more geared towards diesels, as they hold 10 custom tunes. Ive talked to local shops and contacted 5 star tuning a while ago but haven't looked into the tuner lately.
Ive got a full exhaust and an intake on my truck and im just trying to squeeze a little more out of it. Im also not sure if i should go with custom tunes in a different octane other then 87? any help is welcome!

Thanks
