with 24% loss your closer to 265ish hp. i say let it break in, SLS'* with miles on them dyno higher than that
at the same time, with that engine and that gear ratio, you should be able to lay some smoke, have you looked into the computer yet? wonder if its as bad as the new 3.8sc computer in the 2004 gtp'*...

The autotap log we did on his car showed him getting knock, im some cases quite a bit. He may have some sort of restriction in the engine due to an engine built on a Monday or Friday (not quite right) or it may have just been the heat of the day (cars were regestering about 90F) but somethign was off on it.
