I have tried changing out the cop and the same, spark plugs also.
Here is more into the build, the car previously had a 16g
Usdm intake mini
450cc
Stock ecu (5-speed)
Stock fpr
Different tb
Different bov
Different fmic (still have some piping the same)
Evo3 ext mani

And the car did the same thing, right now all of the parts on the car are new.
New intake,tb, tb elbow, gaskets, new injector orings.
There is a few things I have not tried like boost leak, compression test, I do not have a old laptop so I can't log.
And I do need to change out the alternator just went bad yesterday, and my coolant temp sensor is acting up some I will be changing it with the alt in a few days.
