Gordini 182
what sort of power gains can you get from an RStuner map on a standard 172 ?
I want to get mine done too. How much does it cost overall?
Rs Tuner is definitely worth the money. Cold start behavior is drastically improved with the 98RON map. You also have the diagnostic functions whenever you need them rather than having to go to a dealer or garage. (In most cases).
Why? It does a good job, and unless you have supporting mods you won't gain much more if at all.
