Ok guys, I posted this up over at fat pf and have got a few ideas on what to try.
seeing as though a few of you here have fi 1uz I thought I might see if you have any other ideas.
Pretty much the power drops off once the revs get above 4000ish.
Spark is fine according to the dyno op, has a cdi and coil packs.
Ecu is EMS 4244 v4
has WI (snow performance stage 2 kit) which comes on around 5 psi and is on full by at 8-10 psi.
is running on e85, turbo is a gt42 with 1.06 rear.
engine is internally standard
tuned said it wasn't wheels spin/ trans slip (though i will try a run with the converter fully locked)
trans is an mv built a340/341 combo with 3000 stall. supposed to be goo for 450rwkw+
little bit more info here http://www.lextreme.com/forums/showthread.php?t=6548&page=2
here is the dyno sheet
sorry i don't have the afr's. the tuner said he couldn't see anything in the logs that would suggest the problem.

Justen has suggested that it should be around 380rwkw once running correctly
