Tune

[mod]

Can someone in layman's terms explain what's involved in a tune,,
Just things like on a 2.5 STI and STD GT what sort of gains you would get,
And what they actully do to achieve this, and what sort of cost on average we should expect
Thanks

I haven't had a tune yet so I can't input much but whatever is achievable on an STi is the same for a GT-B

with a TBE + proper tune on the dyno for a few hours expect the following from a decent tuner
15-20+ kW ATW
$800-$1000

You will need to let them know what sort of a tune you are looking for, if you want top end power or low end power etc.
Also a lot of people go back to the tuner to refine it a bit more after driving it for a couple of weeks.

There is of course the other way, in which they just slap on an already pre tested tune for someone elses car, change a few things and send you on your way.
As everyones car/mods are different, I wouldn't recommend doing it that way. But it's an option if you want to save a few hundred $

The best advice I can offer is do as much reading and searching on Forums as possible.
Educate yourself on key terms used in Dyno threads.
A dyno is used to simulate road conditions.
Talk to as many tuners as possible about what they do.
That way you build a relationship with the person you feel most comfortable with....and local to you in case there are any issues....did someone say BOOST SPIKE
Research the gear you want to install and pm people requesting their recommendations and disappointments.
Peronally I would NEVER use someone elses tune...not all shoes fit all feet.
The tuner can only do so much to your car....so dont ask for 22psi on a std bottom end.
Ultimately a dyno represents your car performing at WOT....not an ideal situation on the busy roads.
Tuning is about how your car performs in every gear in every rev range.
Have fun
