Dumb Injector Question
Sorry if this is a dumb question.... but can you directly substitute 454 injectors for 350 injectors (TBI)?
I have done a couple of searchs, but many of the results come back with complete 454TBI unit swaps - or is that what has to be done?

Wow fast reply. I am aware of the chipping issue. It looks like I would need to change the BPW Constant down a whole bunch to about 104 from 135 with the 454 injectors (1227747 $42 - no injector constant). I am currently in the infancy stage of chip reprogramming...
Cool. Here is the second part of the question... if you can directly swap in 454 injectors into a 350 tbi unit, why would people bother swapping the entire 454unit?

Hmmm that swap sounds like more pain than gain.
