So I replaced the coil packs, spark plugs and recently got a decent tune. The car ran great, made really good power. This lasted for about a week. Car now feels like stock power and sometimes doesn’t wanna idle like before. Feels like there is a dead stop sometimes between 3k-4K rpm. Can anyone help me out? Feel like maybe the cat is blocked up maybe from when it was running really rich. On my obd2 boost/temp gauge it’s hitting like 7psi which I think is what it was hitting when it was good. But on the exutek computer when it was getting tuned it was hitting 9psi. But of a noob haha. Cheers

Who tuned your car and what other mods do you have? headers will def open up air flow out of the engine.
