From what I have heard...

With non-turbo engines you get the most gain buy increasing the duration of the inlet cam. This raises the rpm range of usable torque, and so increases power as the torque is made at higher rpm. (Power = torque x rpm).

With a turbo engine, it is very different. Mostly the best cams to use on a turbo engine are the stock ones. Note how most turbo upgrade kits on new cars do not include cams, just computer and injectors etc. But to modify a turbo engine, you get the most gains increaasing the duration of the exhaust cam. This is to get exhaust flowing better to the turbo, which inturn increases boost. But this also would raise the rpm range and down low may feel worse, or feel like there is more lag.
