Boost delay
 

So, I found a couple of boost leaks and fixed them with a silicone hose kit. Re-checked and no leaks. However I do still have a problem with severe delay between boost request and actual boost. I don't build boost until 2800 RPM also if I am above 2800 RPM and punch it, I feel the car move, then hesitate then build boost and take off like it should. The car has an APR chip, 034 inlet pipe kit and silicone hose kit. Any thoughts?
