Okay so a couple days ago i picked up a brand new 2010. It now has 500ish miles, and for some reason on the RPD now i make like 200hp tops and it pulls a ton of timing, and knocks like 8*. It didnt do this yesterday, and it still makes full boost. I pulled the battery and it went away, but came back a couple hours later. What the hell is wrong with my car, i just bought it. All ive done is a muffler delete.

 

do you think you got a bad tank of gas? crooked service station selling mid grade, or regular gas out of its premium pumps??

 

filled up from sheetz first using 93, then had less then a quarter of a tank tonight and filled up at speedway, 92. I doubt i got bad gas both times.

 

My KR screen has never shown any KR even though I know it has had knock before.

 

did the cel come on at all? the car will not let you beat on it until it is broken in... how many miles on it again

 

I dunno if its actually knocking but the RPD shows knock and pulls timing to the point where im running 0* and barely making 200 hp, when before the RPDs read like 260. Its very very noticiable power loss.

No it didnt, and it has like 500 miles. And yes it will i know people who have run it hard since day one and nothing like this.
