Not for sure, but early LS3's were dynoing 355 to 360 rwhp. This would roughly apply to the first ten thousand cars. However, now after forty thousand and more cars the dyno results are consistently 370 plus. Same improvements for the L99's. It would seem to me that GM has tweeked the ECM tune over the past short history of our Camaros. It might help to have a recent reflash as pointed out in the earlier post. My 2 cents.
