When do you NEED a tune?

I meant peak MAF, including whatever additional boost you get with the intake.

 

After MAF scale adjustments it was about the same, but voltage was overall down.

 

I'm not sure I can trust g/s as an accurately calculated unit, even with a brand new MAF I've seeing some day to day swings (with similar temps, atmosphere pressures, and humidity). One day it's peaking at ~2.40g/rev another day its peaking at ~2.70g/rev, needless to say it wrecks havoc on my open loop AFR's (one day it's super rich, another day it's super lean).
