I have a greddy turbo kit and a full catback exhaust in my 08 civic si coupe

When i floor my car from 1st-4th gear, it seems to bog at third gear at 6,000 RPM.

From 1-2 all is good and vtec comes in regular at 6,000 and i redline it. From 2-3 all is good, stays in vtec and i shift at redline, but once 3rd gear is in, it drops to about 5,500 RPM and it feels like im redlining at 6,000 RPM and doesn't want to go any further. Any ideas why this is happening? Any suggestions would be great!
