i knew
if you boost you will need a intercooler!!!!
i think the max bhp is reached at 5600rpm (on standard turbo & ECU) you may get it higher with the megga squirt setup
max boost (with an intercooler) on standard internals is 13psi (should put out 185/200bhp)
you can run 17.5 deg BTDC as standard, this gives better off boost performance.
