so i took apart the whole engine today because there was a loud knock noise coming from the inside of the engine. I had KR up around 14, and i am thinking i overboosted the engine. I had the P0121 code also. I was running a 2.8 Pulley, maybe i should of been going to the 3.0 or 3.1. i always use 93 octane. Here are my mods, and attached is a copy of my power tuners bin file. Turns out 6 Chipped Pistons. Pictures Below
