Holley EFI & 6L80
I am building a twin turbo 5.3 that was planned to be hitched to a 6L80 and was going to use the Holley EFI system. I am wanting to use Holley EFI because this set-up will be going into a 1964 C10 that will be street/strip and I really like the abilities the Holley system gives.
I have been told by Holley that the transmission controller that is built into some of the EFI systems will only control the 4L60 and 4L80. I understand that those transmissions function completely different from the 6L80 so that kind of makes sense. Does anyone know or have any experience with using a Holley EFI system in a vehicle that has a 6L80?
