I am tuning for my first time and and pretty confused on where to start at. From some of the threads i've been reading, it sounds like i should start of by tuning my injectors and then do some idle tuning before anything else is done. Is this correct? Also, how do I go about doing so? Basically what i know so far is how to open the "injector flow rate VS kpa vac" table. How do i know what values go into the table at various vacuum points?
Car specifics:
2006 Cobalt sssc
42lb injectors
catback exhaust
cold air intake
long tune headers
Any help would be appreciated alot!
