A few weeks ago I dynoed my car, 01' M6, 100% stock down to the paper filter and it put out, 285hp and 308 tq. It was running rich in the 11.5 A/F range. Wanting to keep this car stock, I added the SLP Blackwing air lid that was an option on SS's. With just swapping "stock" lids I went from 285hp to 307hp and 308tq to 320tq. Now my a/f is in the 13.5 range.

So 307hp/320tq is more like it for a stock LS1 in 95 degree weather

Nice.
It's amazing how much you can get for a hundred bucks when it comes to lids.

Cool. I am glad to finally catch where someone dynoed before and after a lid upgrade. I guess my SLP lid was worth it.
