Honda Problem!!!

Ok, so as some of you know i have a crx ls turbo. A few months ago it wasnt reaching full boost (10 pounds) and it woouldnt reach the redline in 2nd and 3rd gear, it would just float between 4,500 and 6,000 rpm. Hybrid fixed most of the problem by gutting my cat. Now it hits full boost all the time but every now and then it still floats at like 6,000 rpm in 3rd gear and like 5,000 rpm in 4th gear. Can neone tell me what is wrong?
