    315 sounds about right for a 99 WS6 with exhaust and I assume you mean an SLP lid. Are you auto or manual tranny?

    sounds like it is accurate I have a 99 WS6 and had it dynoed completely stock and it put down 271rwhp which equals about 320 at the crank.
    271/.85=318 or 271x15%

    271 is much lower than what many people claim stock. should be closer to 300.
