I have a 2004 and im running a sct tuner and I like running on the performance setting. After a while from riding on it, it throws a p2290 code and gets low on power. So I shut it off and let it sit for a min then start it up again, and its fine for lil while. It wont throw a code on stock setting. What do you guys think it is? Hpop leak, hpop, ipr valve, icp sensor, dummy plugs,ecm,? Im clueless really.
