I CHANGED THE CAMS ON MY 3SGE, GEN 3 TO HKS 264. I HAVE DEGREED THESE CAN CAMS BUT WHAT SHOULD I MONITOR TO CHECK THAT THEY ARE OPTIMISED.

The only real way to see that they are "optimized" is to put the car on a chassis dyno and move the cams about while tuning.

Granted, there will always be some compromise when setting cams on a non vvt motor.

Hey there, 

I ran some tests on a VVTI motor by connecting up a MAF sensor, and then datalogging the output at varying cam advance angles. As per below. 

So it should be fairly easy to see where it's adding airflow (power potential!) without a dyno by looking where you need to add/remove fuel to reach goal AFRs at differening cam angles.

(Then head to dyno to optimise ignition timing etc)
