Do you mean an LS1 PCM? If so, yes, and to be honest, I'd go with a 2002 OS...12212156 is I believe the newest OS you can put into a 99-2002 LS1 PCM.

It's weird I tried it last night and it did not work. I noticed the security light stayed on on the dash. Car would fire for a second then shut off. Loaded the 2 bar back in and it fired right up.

Post what you flashed in. If you don't have the MAF fail stuff set correctly, it'll start/stall instantly like that.

Do you just want a 3-bar capable 99 operating system? Is this for a F-body?

Not all '99 ECMs are created equally. My early '99 Corvette's ECM is not the same as the later '99 ECM that I use in my Nova and they have different enhanced OS choices. You may not be able to run 3-bar OS if you have one of the early ECMs.
