    Sounds fine.

    27 seems low on the freeway, but you must be doing well over 75+ mph, timing falls as speeds increase, aswell as gas mileage. Around 65-70 you'll see near 30ish.

    Well, considering 16* is stock and anything less sucks...

    I'd say don't worry about the cruise timing right now as its fine, worry about the WOT tune.

    What's the AFR? Any KR? What mods?

    If it doesn't knock then get someone to tune it...

    lean it out and up the timing until it does.

    You want at least 16* and I don't care for anything in the 10's AFR wise.
