Default Installed bigger injectors. Left BLM went to 108

Removed my 30# injectors and installed new Racetronix 37# injectors. With the the old ones, the BLM's were rather in check with the left once being in the teens at idle.

I understand the the PCM is pulling fuel to maintain stoich. I have adjusted the injector rate parameter to allow for the bigger injectors. I am also going to switch the O2's to see if that is the problem.

Are there certain other parameters in the tune that need to be checked? Are there parameters that controll the left vs. the right injectors? I am still months away from getting a dyno tune.

There's an injector offset vs battery voltage that needs to be adjusted. Also the Low Pusle Width Injector Offset Adder Vs BPW.

Do these adjustments affect both banks together or the individual banks?
