The only way to sustain 15 psi of boost is under accelaration tuner or no tuner. Cruising will see minimal boost since fuel demand is low. Mine cruises 75 mph at maybe 3 to4 pounds with the tuner on or off. You just don't have enough fuel to produce much boost cruising. I don't know enough about your turbo to know what the max boost on it should be.

 Hope I did not butt in on your question.

@CTcummins24V I run my edge on level 2 and @dripley is right about the boost.  If it's towing or not the best boost I see is 30psi, that's what I set the boost controller at and I don't think my HX turbo would produce much more than that.  I normally drive 65-70 and  tow at  60-65 mph, the boost is 0-5 psi when cruising.

I was just curious. I took off the super b and sold it. The holset is much better down low but seems to choke out around 30psi and higher rpms. Super b had bad low end but incredible mid range and ok top end. Truck is running great and clean with the holset and pulls strong up to 25psi while 30psi and above isn’t pushing any extra power.
