of course its "tuning". In fact, its even called "afc tuning". Is it the best way to "fine tune" a car? no. Is it the same as giving a car a "full tune" - no. Thats the point i was making. Adjusting the boost on your boost controller is technically tuning. The vast majority of people think that afc tuning is the same thing as adjusting the full set of fuel maps, which is the misconception that I was trying the address.
