Re: Just wondering
The CAI is causing the issue, go back to stock hardware setup or make sure the CAI is sealed properly and have the car tuned by a professional. When its tuned they can also lean out the pe some as well. Run E10 or E0 but its not going to fix a vehicles rich condition in general. The way a car adapts during closed loop ltft processing will never be corrected by fuel type change if the maf transfer model is off due to hardware changes. In a full tilt situation E0 is preferred to E10 as it has more potential energy.
