i got this sr20. it has a bigger turbo. at low boost it seems fine but high boost seems like it has a bad boost leak? i checked for boost leaks and cant find any.

Why do you think there is a leak? Does it hold pressure and then drop? Also, if you only checked the fmic couplers, then go ahead and check all the vacuum lines and all seals vacuum related. try squirting throttle body cleaner or something at where the line/seal is during idle and see if the motor stumbles when you do it.
