Default LS3 MAF in an LS1 1Bar Setup

Alright I have a 2000 C5 Corvette with a 408 Stroker, I am making a few changes and will be switching to the LS3 C6 Intake. Because of this I have an LS3 MAF now.
I found the wiring conversion from my LS2 setup I was running to the LS3 but nothing on which table to run for an LS1 PCM to run this MAF.

I could switch to the 2 Bar but I only have the stock 1 Bar and will not be boosting for awhile. I am running the 1 Bar SD Tune with the MAF still on, although I think I will turn it off in the morning so I can driver to work.

Either way it would be nice to find some MAF information for my PCM to use. I noticed mention of changing the IAT and MAF tables so that would be a great start.

Thanks.

Is it a auto car? There is no real need for a 1 bar os upgrade as you can sd tune without it. You would not need to change your maf with a intake swap. On a na 4xx I doubt you would max tge maf out as it is.

What are the steps in doing a speed density tune? It's more than just unplugging the maf, correct? I am having tuning issues apparently my 85mm
z06 maf is maxed out at 5000 rpm I have 98 vette, NA 408 stroker

No it is not an Auto.

1 Bar was done because the annoyance of having two VE Maps on a 2000 OS was easiest to remove by doing a 1 Bar and just not disconnecting the MAF.

The New Maf and Intake were put in to provide clearance for a modification to the hood.
