I checked the coolant and its good, and I did have the TCU sent out but the ECU was done remotely. It could be a plug issue. Since I could not find any posts about cracked pistons on this car I have little go off there. (but it would be much better if it were plugs for me) The guy who had the car before me had an aftermarket intercooler put on, and I told the guy at EC who did the remote tune that when he did it. Im really worried that it may be the piston, since I can't find anything on it and can't find a rebuild kit for this engine. If anyone has had or heard of the pistons not being able to take the extra boost resulting in a cracked or blown or broken piston or rings please let me know.
