s3 cam timing w/ boost

[Butterglry@aol.com]

has anyone dyno-tuned the jwt s3 cams in a det or any other turboed car? im
thinking  about getting some cam gears but i need to know what to set them
at. presently im running a BB det rebuilt with pulsar rods and pistons, most
of the bolt-ons at 14 psi.
the cams seem dead up top like they are loosing power and i hope this will
fix it. before i installed the cams the car was putting 240hp to the wheels,
could the flat spot in the power band be caused by the stock MAF topping out?

thanks in advance
