Default Knock in upper RPMS?? Help.

So i have this terrible tune from turbo trix. I noticed that i got knock from about 5k-7k rpm, when i go full throttle. And if i let the rpms slow rise up w/o boost i can feel the car start to hesitate when i reach 5k rpms. Now, i dont really know much about tuning these cars, but is there anything on the utec i can do to adjust maybe the fuel? to fix this. Could some one give me some insite on this.. and what causes knock.

My mods are: Utec, td05-20g, pe800ccs, fmic, walbro, methol/injection, greddy profec b spec 2 controller, and all other supporting mods.

does the knock happen more after a few hard pulls? if so- your intercooler prolly can't keep up.

It would be best if you posted up some logs. I'm no tuning expert but people have been able to help me in the past after seeing some logs.
