I am also an owner of a ford V8 (289 in my case) in my 66 mustang. i am 
planning on twin turbocharging it as well, there are quite a few turbo related 
computers that are designed for this kind of applacation, some of them piggy 
back into a certin cars computer so are not usefull for turbocharging a ford V8 
but there are others that connect there own way and work independly of the 
rest of the car. as for boost control there are quite a few companys that make 
these computers (boost controllers, Additional injector controllers and turbo 
timers. to name a few there is Greddy, HKS, Blitz, Fet, Ultra, Pivot, Field, 
A'Pexi, M's, and Battle Club. boost controlers can regulate your boost level at 
the turn of a knob or digitally with a high and low boost setting programd in by 
you. AIC's will controol additional injectores usually 6 new injectors. this is 
used fore really high boost situations. and the turbo timer is a device that 
keeps your car running for a set amout of time after you turn it off so that the oil 
in hte turbo baring does not boil and cake to to the baring. this is very important 
to keep the car running relyably.
