Different Carb or EFI

abodyjoe said

if the carb isn't dead balls on in its tune then the efi can and will improve performance quite a bit.


this guy saw a 5 mpg gain. and says the car feels better. said the carb ran good to. hat to be way out of tune.. http://board.moparts.org/ubbthreads/showflat.php?Cat=0&Number=7331071&an=0&page=1#Post7331071

You talked about how next time you would go with a system where you could get parts from local store. What kind of system would you think of? and what would be price difference going to direct injection instead of the carb style efi?


I also got this off a site where the guy emailed FAST.
"The reason we don't advise it with nitrous oxide is because this system is always in closed loop. If you go to wide-open throttle, it tunes to your WOT air/fuel ratio target that you have set. If you spray nitrous, it doesn't know this, and it will try to keep the air/fuel ratio at the target you have selected for normally aspirated. This is normally too lean for nitrous; it would lean the mixture out to an undesirable point. There are guys running nitrous with it, but they're setting their WOT air/fuel ratio to what they want when the nitrous is on. This will obviously work for the track, and conceivably you could change the tune before you drive home-so it's possible, just not recommended."
