Default car revs fast and hard to 7000rpm then it struggles the rest of the way

why would my car be doing this?? i have a LS/VTEC turbo and the way the setup is my car should be pulling harder and faster the more i rev it. but instead it carries to 7000rpm very fast but rite after 7100 rpm it doesnt like to rev up any more. i have revved the car to 8000rpm but only once and even then it struggled to do it. the motor is built so its safe up to 11000rpm but i have my redline set to 9000rpm for breaking it in. the motor now has 800 miles but still wont rev all the way up.

well heres my set up :
ls/vtec fully built
8.5:1 or 9:1 on compression
550 rc injectors
60 trim turbo
timing IS correct
valve adjustment IS correct (cant hear ANY valve tapping)
timing is retarded at the dizzy

i have the walbro fuel pump but its not installed yet. do you think this could be the answer. i need help, and appreciate any one willing to help. but please dont comment if you dont know what you are talking about.

put the fuel pump in. set the ignition timing correctly at the distributor and tow the car to a good tuner because you obviously have no idea what you are doing.

Default

it is the fuel pump.. and if you dont put it in you will blow up your engine... if you dont take it somewhere to be tuned you will blow up your engine.. if you dont put oil in it you will blow up your engine..
