HY!
i had 230 RWHP and 322Nm, only mods BFI, IK20 plugs, EGR off and Pro-Speed Muffler, and only near 28tmiles on my 97 SC400. It runs to rich under full throttle (10:1) i think, with a SAFC or a piggypack it goeas a little bit more, i removed the 3rd converter,.... this year maybe a dyno with the W58 swap.

Stock vvt-i's dyno around 220-230hp iirc. There's a thread about it somwhere. I'd say a 50-60 hp increase with a simple BFI and exhaust is pretty damn good (although I know a lot of research work went into this exhaust to allow for the most hp possible).
As for trannies, mine is still the stock auto. Auto trannies normally give you about 30% hp loss through the drivetrain. Manuals are supposed to be only a 15% loss. I'm planning on a R154 swap (hopefully sometime this year) and a piggyback tune after that, hoping to increase those 270hp numbers a bit

You said your dyno figures are not at the wheels, and the sheet says flywheel, so I'm wondering why, with those mods, isn't it higher than the stock 290hp which is what it's supposed to be making at the flywheel without modification? Or am I reading it wrong?
Now if it were making 270hp at the wheels with the mods you listed, that would make more sense to me since the headers alone should be making a good 20+whp?
