It sounds like a Subie with exhaust.. escpecially when the car is moving at low speeds it sounds like subie

That sounds like an exhaust leak, or else I'm completely misunderstanding what you're trying to describe. Also, if you've replaced the spark plugs recently, you might have forgot to tighten one.

Is this a mechanical clattering noise, or a funny exhaust noise?

i did change the spark plugs bout a month ago,

NasTHatch

you are running on 3 cylinders. so turn the car on and let it run, then pull the plug wires out of the head one at a time, when you pull one out and it doesn't change the motor, you found your dead cylinder..

could be cracked ringlands, bad rings, you might dropped a valve and had piston to valve contact which would make a lot of noise ....

Or properly torque the spark plugs. My cousin installed new spark plugs and 1 wasn't tight = Subiesound!

so just curious as to what your fuel management is. is it top secret or non-existent based on your lack of answer?

not for nothin but check the valve spring retainers i had one break on me b4 and the car still ran but it sounded horrible inside the head but first things first did you pull the valve cover and even look in their yet?

GSRswapEk

ya pulled valve cover and my friend checked a few things, was gonna do a compression test but didnt get time to,... and my fuel management is DSM 450cc injectors on a basemap

So you've been running that turbo setup every day for a few months on a basemap.......................................?

Turn up the boost and see if it gets worse please. It'll help with our Diagnosis.

Laserjock

Awesome. I suggest turning up the boost +10psi more. You are not taking advantage of that tune.

It'll run much better in this temperature
