There're many different combo of wheels, compressor housings and exhaust housings for TD06s. You can choose a wheel from 13C - 25G, exhaust housing from 8 cm2 - 16 cm2. Power output and lag depends on the combo. 20Gs (not to be confused with TD05 with 20G wheel) with a 10 cm2 exhaust housing will probably make 650rwhp on pump gas. But the full boost will be after 6000rpm.
