It seems that ever since I installed the RJC 5"DP and 4" exhaust that the car runs pig rich. The exhaust smell is so bad that you can't even be at the rear of the car when it is in the garage because it burns. Also, really gaseous when in open air. Not sure what to do first, but have checked the oil and it is gassy smelling and not excited about that because of cylinder washout. Currently running 60lb injectors and test pipe. Need tune help, but don't want to lean it out and have bigger issues.
