I have had several over 500whp on stock engines.. With stock everything including exhaust it you can expect 240 to 280whp depending on the dyno that was used.

I put down 275whp and 270wtq on a dynojet. Thats an 07 sti motor swapped into my 99 RS. The motor put down those numbers completely stock, from the air filter to the tailpipe. Here's a link to my thread with the dyno chart:

I've got an XPT tune on my 07' STI. I didn't need to port anything, I just needed to adjust my wastegate duty following Braden's directions. Before adjusting, it would overboost to fuel cut in 4, 5, and 6 gear pulls almost every time.

I made 252 before, I haven't gotten back to the dyno yet...
