What is a "tune"?

So I've heard some people talking about a "tune" or "Tuner". Something you hook up to the PCM. I'm wondering if anyone can give me some info on just what a tuner is and how it works, maybe where to find the best one.
 


a tune is modifying the file on the PCM in order to get more power and/or better driveability out of the car.

a tuner allows you to do this by being able to pull, edit, and push the files. for tuners you really only have two options: HPTuners or DHP Powertuner (which is no longer made and you'll only find it used).
 
Thanks, Is it pretty easy to do, or something I need to leave to a pro? I mean I'm pretty DIY and I'd love to but I know I have limits. And what amI looking at price wise?
 
all i can say before you try tuning yourself...RESEARCH RESEARCH RESEARCH

it can be an involved process.

price wise, i'd say you're anywhere in between $200-$350 depending on seller
 
dont mean to threadjack but my questions goes along with the topic, when should i tune? i have a friend with a tuner and im just curious after which mods i should tune the car, or does it need to be just once?
 


pulley drops equal tune time
meth equals tune time
n2o equals tune time

Any major mod you should tune for even a complete stock car should be tuned
 
is there such a thing as tuning to much? i know dumb questions but i have to ask. made a fwi, and hopefully a dp soon, tune after that? new plugs and wires and tstat, tune after that too? and then the 3.4 pulley and tune(i know that much)
 
first tune should come with the pulley drop no need to tune for every little change

i have a basic mail order tune and ill run it even with my 3.2 drop but will dyno tune when i add meth
 
depends if you have a compitent tuner if your not modding that far id say get a mail order and your in bussiness
ALl depends what your looking to do
 


i have a short ram intake, a good set of racing wires, what else do i need, or would be recommended to install before doing a 3.4 pulley drop? i just found a guy that can dyno tune my car.
 
what headers for california? what are you running? i'd like them to be smog legal
what about PEM?
i meant to put 3.6, as that is what i am planning.
 


Only one smog legal header and its TOG's they are pricey
i also dont know abot 04+ i know there legal on 97-03

I ported the crap out of my from mani and am having a dp made with out the dp though i have zero kr But im also cammed so i dont know how much that plays

Id say PEM's and a dp youl be good to go with a good tune
