No power at higher RPMs?

I had a vacuum leak on the valve cover. My long term fuel trims were +28% and would drop to 3% when higher rpms. I fixed the leak and now it's reading -13% at lower rpm and to -2% ish under load. My turbo is spooling and my coolant Temps are fine, but if I'm going up hill I can feel significant power drop off. I had a level 2 tune done after I put in a bigger intercooler and catless downpipe on. When I hit about 3000rpm my car used to really pull and you can feel a big difference in horsepower when the turbo kicks in. I'm getting none of that now. My low end torque is fine, but it's like the turbo, even though spinning, isn't doing anything. I've also noticed that once I get to a certain point on the accelerator it just stops changing anything. I can push the pedal further but my instant gas mileage doesn't change and none of my readings change even if I bounce the pedal in and out. It's like the ECU won't let it do what it's supposed to do. Everything seems to be working, but just not as expected. I have no engine codes whatsoever. I have 2 mid grade OBDII scanners and there are no errors. Could it be the ecu needs reset, or is there some other issue I need to be looking for?
