Is multiport injection worth the extra cost??

TBI is fantastic , night and day over a carb. Easy to install and less than half the price of MPI . Like I said night and day over a carb the difference between TBI vs MPI is just about 45 minutes.

45 minutes? I don't know about you, but I can't change an intake manifold in 45 minutes - and that's something I definitely have to do for MPFI, but don't have to do for TBI.

I took the 45 minutes reference to mean the performance difference between carb and TBI is day and night (figuratively twelve hours), while the performance difference between TBI and MPFI is much less (45 minutes compared to 12 hours). I doubt he was referring to installation time.
