Im at 274 whp without a downpipe or tune (on mustang dyno). I don't think 350 is possible without a bigger turbo. Full bolt ons and a tune on stock turbo you are prob looking at around 325ish.
Well, you and I have similar mods, so I'd guess with the AP I could probably hit around 290-295 on the dyno.
350 is achievable, but not too many guys will put the money in to do it correctly.
