I am getting a used engine for a subaru impreza turbo 2000,1999. As I am getting my engine changed i will be upgrading my turbo to a vf 28 turbo and an STI top mount intercooler, my question is would it run fine without a map am i able to drive it as normal or do i HAVE to get a map?
The person putting the engine in says it is fine and does not NEED a map any views and help.
