I installed mine in an afternoon
I had no tuning knowledge other than reading the dynamic efi web site . No additional hardware to install and wire. Uses all stock GM sensors I Was up and driving same day ....If you choose to add options like wide band sensor then additional work is required but that is with any unit.
Thank you Bob, as this is exactly what I was referring to. When I stated up top that there was some repinning as well as modifications to the stock wiring harness that were needed, but that it was minor, I both said that and used the term minor in contrast to running FAST and the other systems, which require a lot more work to get the engine up and running. Not sure why it was taken out of context.
But I digress...
Excellent times by the way, congratulations...
