MAF voltage = 100% IDC when???

[farfrumwork]

So I finally was out this AM metering the output from my MAF sensor to see where I was before throwing a FCD in.

I found that I am getting max 4.65v at the top of 4th gear (about the same as I see at the top of 3rd).

Once my FCD is in, how far should I push the voltage output?? Can I add boost until I see 4.75v? 4.8v? 4.9v?

I know that the warm summer air will yield lower outputs at the same boost levels, so I will be revisiting this once fall hits and deriving "summer" and "winter" boost levels that are safe for the stock fueling system. I was just wodering if anybody actually knew when the ECU will throw the injectors 100% (i.e. will it go 100% before 5.0v)

Thanks,
Chad

btw, altitude changes these readings dramatically (duh). My 4.65v is seen at 12-13psi (still 11+psi at redline) here at 5500ft asl. I think I can run close to 15psi and still be <5.0v. This is on a VF12 (3" CES, A/W IC, etc).

The NA ecu can take right up to 5.0 volts (I clamp it at 4.9 though) and be fine. However, the moment it goes over 5.0, WEIRD stuff can happen.

As for the turbo ECU, I am not sure, but I would not want to chance it too far.
