I am not saying better or worst but fact is that FF-CNG was problematic... It's tuning was possible only at dealership due to proprietary software + the coils failure problem + the poor consumption & the poor pick problem on CNG due to slight improper tunning. If you replace the FF injectors CNG kit version with the normal Landi Renzo Kit, most problems get settled.
Agreed to some extent.
I have given my stance above
