I've been reading all day and there are no straight answers. Is it worth the upgrade? That's really all I need to know. This will be on an 03 truck.
UDC!
No stay with the vin locked TNTR I wish I would have never changed mine and you can't go back to the old vin locked TNTR once the new program is loaded.
The Vin locked tntr was better than the new tntr on my truck but quit waiting on efi, IMO it's not gonna happen for 03-05 and get UDC, it'll do everything you need in a custom tune.
