Hello, I need some serious help. I just did a 351w swap in my 87 Mustang GT. I have 30lb injectors with a 75mm MAF sensor that is calibrated for them. I also have BBK 75mm throttle body and a Aeromotive adjustable fuel regulator. Now when I take off, the engine starts sputtering but when I engage the clutch I revs up fine but soon as start disengage the clutch again to take off the engine starts sputtering again and blowing black smoke out the back. My whole ignition system is MSD. I do have a stock fuel pump which is soon to be replaced, but I don't think thats the problem. I have lots of other mods that I have done to the engine, but I don't think thats relavent to the problem. Please help! Thanks.
