The first thing I would advise is to get it to a dyno and monitor air/fuel.Pending the outcome and if it is indeed a tip in rich condition you may consider the MAP sensor.The MAP on a speed density car is soo critical to driveability.If the map is good and A/F is still an issue believe it or not the condition of the motor can affect A/F due to the MAP relying on vacuum and or atmospheric pressure inputs to tune.That is in direct relation to the volumetric efficiency of the motor.The motor has to be healthy for speed density to run the vehicle 100%.Also check full sweep on the TPS,the vacuum source to be free of holes or cracks going to the MAP,and fuel pressure.The pressure w/ vacuum should be in the 30 to 34 range,w/o should be in the 34 to 40 range.Hope that was helpful.
