Piggy Back Injectors

[Roger Heflin]

Tom,

Someone on the f-body list is running a device called the Caroll
Superfueler, I believe he said it puts additional fuel in at the
throttle body so it would be a combination.  The guy running it has a
modified motor and a blower, so the stock injectors aren't enough to do
the job.  I am not sure what conditions can be set to cause those
injectors to be used.  I would hope it had a fairly configurable
controller so things could be adjusted optimally.  I guess that if
someone was building their own EFI computer there would be nothing
stopping makeing the system use both, so you could get both drivablilty
and good gas mileage and lots of power at wot.
