That is, not maximizing the potential of an SGI kit.
You would not be able to use the kit's full potential. It will be operating based on a fixed fuel curve. The fuel curve may or may not be optimum for the driving condition you will be experiencing. This will include problems if you have a dirty air filter, change in altitude, etc.

In the end, it will be operating exactly like the venturi-mixer auto-lpg kit but with a more expensive installation bill.


If possible to equip without an O2 sensor, can I subsequently install an O2 sensor after the SGI kit installation? I heard that the O2 sensor seems to be expensive.
Yes you can, but it is expensive.
