No long tubes, these numbers are with a Corsa Air Intake and a Corsa cat back Exhaust.

Well then those are good numbers for an L99 withouy LT's.. Like I said, mine put down 332 on the mustang dyno, with just those mods, which in turn would be about 342 or so on a dynojet.. They usually show around 8-10 hp more than a mustabg dyno. At least that's what I've seen on this forum. So you are golden with 345. Add some LT's down the road, and hello!! Plus it will make it louder. If you like that. When I did my LT'S, the sound seemed like it doubled..
