Using TBI on moded 5.7

[Tom Sharpe]

(Bandaids) Imagine the fuel curve on a piece of graph paper. Twiddeling the TPS
moves the slope left and right. Diddling the fuel pressure moves it up and down. It
the fuel curve is reasonably close, shape wise, you might get close enough to drive
it, but it won't be right until you start burning chips.  Just MHO  Tom
