Hello everyone. Maybe someone has some answers for me. when my car is cold, it sputters and blows alot of black smoke. As it warms up, runs great. Any ideas? Plugs? Tuning? Turbo?
No doubt the CPE pump will help at the high end (high pressure requirements) during warm up I don't know why this would be an issue. The KMD internals have a good rep so unless you have some logs that show this is an issue, I might look somewhere else.just spoke with tuner, he said it is most likely the FP. Logged the fuel pressure. Guess its time for a CPE pump. KMD internals not working so good
