Could you guys look at this tune & tell me what you think? It is from a 2002 stock firebird ls1, 1-3/4" Headers, no cats, ported stock tb, stock MAP.

PE looks way off.

Can you Explain PE looks way off?
I copied this from a car that runs really well. It is set up, to retard the timing for Nitrous. Which I would not use at first.
But as I am starting to learn the different maps, I don't want to go down the wrong path.
Thanks,

Copying from a car that "runs well" means nothing. Also, running well and correct are not the same. You are commanding lean AFRs at 4000 and below, then towards the top quite rich.

The EQs in the lower RPM range are a bit on the lean side of maximum power, but they don't seem terrible, especially if you're more concerned with fuel efficiency than maximum power throughout the operating range. The PE seems to get excessive at 6k, but for a stock LS1 the redline is 6200 and I believe the optimal shift point is below 6k, so I would think the enrichment might be set high there to cool the charge and prevent knock as the engine is getting towards being over-revved?
I'm not an experienced tuner - Am I wrong?
The difference in fuel eff vs. running a richer (less risky for spark knock) mixture will probably never be noticed.
