Correct Ian,

As mentioned good boost,torque,power and so on Is the result of the support mods from cams,fueling,Ignition,down pipe exhaust,cooling and so on.My boost raised Itself from 1 BAR to 1.273 bAR when the Apexi N1 free flowing 3" exhaust was fitted.

No boost unit has ever been fitted.Back to One bar with the HKS exhaust but more mid range torque.Now at 1.34 1.36 BAR with the CT 20 B Rally Turbo which has a massive exhaust size and fully ported all round.

Technically speaking It Is maxing out the OEM ECU,but easily contained by fitting a boost control unit say to 1.2 bar stable and of course till then not drive past 1.1 BAR.Got an FC to be mappped at 1.3 BAR but will probably set the commander boost at a maximum of 1.1 or 1.2 BAR.

Main point as skip123,points out the rev 3 ECU is very good yes runs richer and uses more fuel but as Jonb was told at the mappers It means the engine will last forever.
