I was going down road today and wondering why my car felt like a dog......come to find out my car is only boosting a little over 4.5 lbs........I have a profec b spec 2 on the car and had the car tuned on 10lbs......i don't know if the tune was just showing that the turbo was spiking to 10 lbs....but sometimes the car will go to 10lbs and the other 95% of the time the boost sticks at the stock wastegate boost setting.........please help.......
