I've seen as low as 240 and as high as 270 depending on the dyno. The only way to get a true baseline is to do a baseline power pull.

+1. Results vary. Best to do a baseline and then use the same dyno after your mods are installed.

Using same dyno for before and after...good idea. Hadn't thought about that. Thanks.

Yes using the same dyno is important because there can be serious differences from one shop to another. Generally you can assume a 15% loss on manuals, and like a 20% on autos.
