Custom tune?
cause I'm not gettin jack. Tried stage 1, then 2, now I'm fartin' around with +4 shift points and bumopin' up the rev limiter +400 rpm. To make a long story short
should I be like "damn" or should I have someone custom tune it. I got your average mods on my a4.
The purpose they serve is mostly to give a simple way of adjusting for gears and changing fan temps, along with scanning and clearing trouble codes. There really isn't much benefit in changing shift points/rev limiters on stock cars, and many people agree that transmission pressure changes aren't worth it.
If your main goal here is power then the money is better spent on a professional tune (if your mods are done) or a tuning suite (if you have the time and ability to learn yourself).
