[s-cars] Re: wrt pushing RS2 to the edge...

[Mihnea Cotet]

Only one comment on your email, if most tuners disable altitude
compensation  in UrS chips, I'm sorry but they need to study their map
descriptions again, it is stated quite clearly inside how to compensate for
altitude and I can't see why they would disable altitude compensation. My
chips always retain that kind of factory security setting and I can say
with no fear that the tuner who suppresses the altitude compensation is a
huge dumba$$.

No further comments, basically we ain't talking the same language. Stay at
2.4 PR and have fun there, I won't go indefinitely at 2.8, maybe only 2.6
but I surely won't stay at 2.3-2.4, and sorry to say that if almost all
*real* tuners in Europe do that (i.e. sell chips with 2.8 Overboost when
it's not 3.0), they must know their stuff better.
