As some of you know I've had some horrible drivability issues with my car. A lot of time was spent trying to diagnose the problem. Kevin @ KC (Underground Racing)tuned, retuned, checked, and re-checked the entire system multiple times. They added an AEM thinking this would fix the assumed tuning issues. After adding the AEM the car went from driveable to UN-driveable. It started bucking, surging, stumbling, etc.... I couldn't even drive it to the store a couple miles away. I became very frustrated. I thought about selling the car but realized that I couldn't sell it with it not running, I even thought about getting another tuner to work on it. Fortunately, I decided to give Underground another chance. Turns out that when I had the Roe blower on, my car had the rear "ground" done. We disconnected the ground put the cover back on as well as the rear wheel and fired it up. The car immediately sounded different, and the idle was smooth and steady. We then backed it out of the garage and took it for a ride. The bucking was completely gone and the car accellerated up through the rpm range very smoothly and precise. No missing, bogging, or stumbling was present. We did several highway high speed, high boost runs and the car ran perfect. I couldn't believe it, something so small created so much frustration. Anyway, just wanted to let everyone know the car is fixed. A big THANK YOU to Kevin and KC @ Underground Racing for not giving up and sticking with it until it was fixed.
