Yeh, the 89's were speed density, but the computer was designed to make
power, not be emmisions whatever. My friend has a 89 in the high 12's and
he is running the stock computer. Whatever he does, the car learns it in
about 5 miles and he gets faster. Our trucks really are limited by this
system. I was thinking about how much effort it would take to switch to a
ford system. What would you do about the transmission, isnt some of it
ran off the computer? If it wernt for that, we are using ford injectors.
One of those airraid tubes could have a mass air on the end of it. It
might could work.
