I tried to get a response for my other posts, but I was hoping a dedicated thread might be more fruitful. I am going to get a turbocharger put on my car, and I ahve the option of an standalone ECU or piggyback. I hav had a chipped audi, but have no experience with a standalone ECU. I was hoping that some people have had experience with a standalone and can relay what their experiences ahve been like. I don't care about getting eveyr last possible hp out of the car. I want a large saftey margin on the car, and I don't want to have to tinker everyday to make sure it starts. I want my car to be emissions complient, but I don't know if emissions use a OBDII port to check for these emmissions. I can get a standalone for 500 dolars more than the piggyback, but I don't want to suffer drivability issues like stalling or damage my engine. What are your thoughts?
