    Numbers look close, as previous guy stated, dyno numbers will vary.

    YBNormal's STi at sea level produced 305whp, not sure about the torque. And that was just with an accessport tune I believe.

    Bottom line is, on 93 octane, expect 300whp with a TBE and a accessport/ecutek/utec tune. 344 whp is on race gas. no matter the sea level you should be able to achieve at least 295-300 whp. I also checked out the wheel torque, and at 305whp you can push it to around 342 torque.

    Oh of course, race gas burns the slowest of all the fuels, so the engine just loves it. And race gas is 110 octane.

    Sorry to hijack the thread, but who sells racing fuel? I know there's a place nearby that sells's 100 octane, but I've never seen 110...

    As posted by whit above..see sig below.

    FYI..yes...race gas does make a huge difference as long as you can tune for it...otherwise it doesn't do much on a 93 tune.
