ok so heres my issue have a teggy wit a jdm b20 and it is running rich as all hell. i have a stock fuel pump and injectors and a after market fpr. (its AEM) it was running rich before i replaced the stock fpr. I have the gauge for the fp and its at 44psi and i have no check engine. I have a P72 ecu chipped with a base map and disabled the o2 sensor so i dont think thats it. An when in idle it sounds like a lawn mower it goes up and down i cleaned the iac but I HAVE NO CLUE please help my fellow teggy owners cuz im stuck lol
