(Thread Starter) |   Not Ranked : 0 score  Weird boost cut issue My only two "mods" -Cobb SF Intake, no TIP -gutted secondary cat So, on my way home from work today, I did a second gear pull, I make a little amount of boost, then car lost power, starting bucking almost like a hard misfire, no CEL, did it in 3rd gear too. Car runs fine other than this problem. My guess is that its either a boost leak, or a fuel pump issue? Maybe you guys could help me, thanks! |

| Not Ranked : 0 score Get an AP, post a log. But it seems you're getting either a boost or fuel cut. That gutted cat might be causing you to overboost. |
