You can look at your A/F Learning 1 A,B,C,D fuel trims over time which is a good method to determine if there are any intake leaks or other fueling related issues that are manifested in closed loop. It can take some time for these to populate accurately since the last time they are cleared which happens when you install the AccessPORT, reflash a new map, reset the ECU or disconnect the car's battery. Each individual fuel trim should be within around +/- 5%.
