Chris-sit tight on any mechanical work for the time being. In my opinion it's an odds-on bet it's your spark timing. The likelyhood of there being a mechanical issue here is vanishingly small. Although you mention someone making 400rwhp on a stock ECU, you aren't running a stock ecu. You have duties split between the wolf and the stock ECU, which may be affecting the stock ECU and the way it times the motor. Considering the size of the turbo, piping, FMIC etc, even the 182 at 15pound sounds a bit low.

A compressor wheel that big will be swallowing gob loads of air at 15psi. To give you an example, my 1FZ with the 66mm comp wheel GT42 was pushing 320rwkw on just under 15psi. The TA wheel shouldn't be too far behind.

If the engine was actually struggling to 182@15psi and the timing was normal (I'm guessing 19deg+ or so on 15psi in a 1J should be around the mark), the blower should be virtually in surge condition at the (relatively) minor mass flow required for that power level.

Given your intake temps were in a perfectly acceptable range, it suggests that the turbo was in fact injesting the craploads of air it should at 15psi. Also however, my guess is that the spark timing was so retarded that the engine was producing far less power than it could have with that amount of air going through it. Get control over the spark to confirm or deny the issue before you start pulling bits off.

At least you now know it all works mechanically. You could disconnect the auto trans altogether and run the wolf for the spark as a trial. With all wires disconnected the trans will shift 1-3-4 in 1st, 2nd and 3rd(drive) on the stick respectively. This is fine for acceleration runs in 2nd on the shifter as the box will be in 3rd, or 1:1. It won't hurt the box as long as you dont hammer it from 1st to 2nd(on the stick), as the box will actually slip through 2nd on its way from 1st to 3rd-frying shit as it does so(I know....)

Have you ordered the shift box yet, and does your trans have a cable coming out of it (line pressure cable)?
(do you want me to ask mike when I'm there next?)
