CA18DET lacks power after 3000 rpm n no boost

[Rambo24o]

Hello I hope some one can help me.. Well I started by checking
turbo leaks.. I have none... I check to see if the ecu has s code
It reads nothing I dont have a O2 sensor, dont know if it can be this
But any help will be appreciated thank you....

You will need to connect your 02 sensor or you will have problems. Do you have the knock sensor hooked-up? If your ecu is displaying no codes, then something is worng with the way you're testing for codes or the ecu is going through some issues. This also sounds like you have a wastegate leak. If there is no boost at 3000rpm, then you are losing boost. Sounds like you have some issues that will require you to take your time and go over everything slowly to make sure you've crossed your "I"s and dotted your "T"s.
