I have a td06-20g with a 16cm2 exhaust housing. It should be tuned in the next 4-5 weeks, currently sitting on the stock manifold and with a stock ecu. Makes 344hp @ 13psi, full boost by 4600rpm. I expect boost to come on quicker once the ecu is fitted, if it isnt much better I'll look into a tubular manifold. I'll let you know how I go, but I expect to make 360ish with the ecu and around 14psi.
