[BiturboS4] New S4 owner

[Al Adler]

I'm sure Audi had the California's  91 octane  in mind when they detuned
so they didn't have to have a CA specific version since CA gets the
worst gas in the US. If I want to pay through the nose I think I can
even still get 95 octane at Sunoco here in VA, but even so its 93
everywhere else.  As for the slushbox(which I'll sheepishly admit I have
because of the traffic around here) its rated for 300 ft/lb according to
AMS - they detune their chips for the tiptronic version so as to not
exceed that value.

As for you APR chip owners that don't have the CEL problems - are you
running the new V5 software or the older V3 software? Mine is the V3 and
I'm wondering if upgrading it will help with my CEL situation.

Thanks
Al

As for the detuning of the S4 from 265 to 250hp, I thought the main reason was so that Audi could equip this car with a slushbox for the North American market, as the euro-S4 are manual transmission only.  The main reduction is torque from 295(?) to 258(?) ft-lb, my numbers maybe wrong.
