No check engine codes and idles and drives fine but no power. I am sure it is not a boost leak since it idles fine no hunting idle or missing. This XT is 100% stock. I have been reading the raw ECU code and is it possible if one of the Catalytic converts clogs that the ECU from the EGT reading is not allowing the waste gate to close to prevent damage. It was past time for the timing belt and I replaced it thinking maybe it had skipped some teeth but this did not resolve the problem. I really don't think the exhaust feels healthy or not enough air pumping out at idle but then no way of determining that. Searched a hundred different ways but could not find a match to my problem. Thanks.
