New engine start up

  1. Im currently building an engine for my car and am going to turbo it. Im curious if the stock tune is safe enough to break the engine in before i have it dyno tuned or if i should get a pre tuned chip the will be close for initial start up?
  2. is it still a 302? if so, it should run, but definately stay out of boost until you get a tune for it. otherwise, you'll probably be taking it apart again!
  3. It depends on what kind of engine it is. If it has a big camshaft, the intake vacuum at idle will drop below the range the stock tune can function with, and it will be undriveable. My car simply will not function without a chip. It idles at 1700 rpms, throws a check engine light, and runs so rich it chokes out the neighborhood. SCT offers a deal where you can get a chip with a basic tune based on your build information for $265, and then when you get the car broken in, you can take it to an SCT dealer, and they reflash the same chip.
