I know nothing about fuel controllers, so please forgive a dumb question. One of my buddies told me that the fuel controllers were great, but you immediately lost the flexibility of OEM fuel injection with them. As in, I'd run better at 1800ft or whatever I'm at here, but wouldn't run when I go on a mountain trip up to 11,000ft. Is this true? It seems like that with a piggyback controller like this, the OEM computer could still change the variables it needed to.
