Bill's is making the std 6 lbs .... Can anyone predict what his curves would look like if he was doing 8 lbs .... or perhaps even 10 lbs on the boost.
Bill ... do you use a boost controller? If so .. have you turned it up a notch or two yet?

boost really isn't ramping up very quickly in relation to RPMs so the torq curve is following the boost.
looks like boost is coming on a bit slow IMHO. I'd like to see over 5 psi by 3k RPMS which seems doable.

The boost ramp/torque does look a little soft. I wonder if it's related to turbo sizing or the kit itself (that's a legitimate question, not a poke at the STS kit). I just pulled up a log I had of my TTiX building boost and it had 7psi by 4000RPM (I later found out that my wastegate vac/boost connection had a tear in it, too) and hit full boost by 4400. Others have reported full boost in their X kit in the 4000RPM range.
Does anyone else have a dyno chart with boost pressure across RPM for the STS kit?
