Hydra EMS controls lift point. There is a guy with a Corolla XRS on Matrixowners.com (Potter) who used Hydra EMS to change lift to 5700 - 8600 rpm. With intake/exhaust/ported header/lift tunning he dyno'ed at 185 whp. The variable valve timing MUST be tuned along with lift otherwise, the car actually loses a lot of power despite the lower lift.
Monkey wrench racing is making a harness for Corolla/Matrix XRS for the 2ZZ Apexi PFC, which will essentially do the same. I personally will take PFC over Hydra EMS.
