Most vague post ever. Make a video of what it's doing. Do you have any performance shops near you? You could potentially be hurting your motor, depending on what's actually going on.

It could be a ton of things. Could be a boost leak, could have damaged compressor wheel, could be a valvetrain problem, or a fuel/ignition problem. Boost adds a lot of complexity when it comes to troubleshooting, unfortunately.

It could be your flux capacitors.

+1 to not banging on the car until you check it out!

cutting out as you mention could be a boost leak...seen it happen on an evo during revs while looking for the leak....

could start there, but a full inspection sounds in order

sounds like a boost leak somewhere...you need to get a full inspection of the system
