curve will be somewhat flatter than stock. If you go too big of a cam then you will loose some mid and low range torque as well as possible laggier turbo spool up time. Ajustable cam gears let you fine tune your cams for the best performance by adjusting the overlap.
I had the JUN 256 9.5 mm cams and noticed no difference in idle quality. It is a some what a mild cam. But my torque increased by about 130 ft. lbs at 18 psi @ 6000 rpm vs the stock cams at the same boost level. Of course I had upgraded turbos as well. My peak torque was close to stock at 18 psi about 10 ft lbs. higher. 440 ft lbs vs 450 ft lbs.
