yes i know u dont need a chip to be tuned...thus this is why it only cost $200 approx. and yes if u have the tables of how much timing to pull for x amount of shot size you can safe adjust your timing, but i personally feel that by taking it to a shop, having an expert do it, youll not only know your afr is correct but also will be able to see at what point your making the most hp (as far as afr and timing).
and for the anti-tune thing, in my very first thread 6-7 months ago on here, i had a problem with my car and no one on here had any clue as to what to do besides tear everything apart and replace the plugs, wires, distributor, fuel injectors and so on, you insisted in that route instead of taking my car to a shop and having it checked out on a dyno to see if its pwer was correct, low and behold the timing and afr was way off.... now most completely stock cars dont come with wierd things like that. thus why this was overlooked. and i saved a ton of time and money!!
