Hi guys. Just one question. If i swith to a bigger injector; 560cc, is it possible to have a negative value in my fuel table at the lower rpm, in vacum row?

Nope. What exactly is the problem you are seeing?

When i switch from 310cc to 550cc injector and retune, the tuner did not change the injector size in flashpro manager with the reason that if we change the input to 550cc, we will have a negative value at lower rpm and pressure. I am not very convinced by him as in my opinion we should give an accurate input to get the best result.

It sounds like it may be time to find a different tuner as this information is incorrect and changing the injector size is the first thing that should be done and it will not change the values in the tables at all.

That statement really help. Thank you.
