Thank you for your interest in Revo Technik.

Although we have S4 software available in Europe, we don't expect our

tuning of the US spec cars to be ready until December. We will have the

performance software ready in early December for stock turbochargers and

software for K04 powered cars later in December.

The North American biturbo S4 has different engine output characteristics.
The US stock S4 specs are 250 hp/258 lb-ft, but the ROW (rest of world)
S4 is 265 hp/295 lb-ft. The engine codes are different: US: APB, ROW: AGB
The ECU has different programming in it, and the transmission has different
gear ratios, but I don't know if there are other mechanical differences.

Probably Revo just never got around to developing a US version of the
S4 firmware yet.
