I currently have a basemap on my car just to drive on, but it idle surges like I have a vacuum leak somewhere, but I do not have any leaks. I'm running precision 780cc injectors onmy b16a. Stock block. Will I idle funny/surge if my car is not tuned on these injectors? Also if it smokes does that mean its the map also? I replaced my old turbo and mani with a new one and the tuner here locally did something to the map so now it smokes more then what it did. So is my basemap messed up/? Too much fuel, not enough?
