    • ABT tunes the 4.0 TFSI Turbo motor in the Audi S8 to 612 horsepower - +100 horsepower

      The 4.0 TFSI tuning market should really get going fairly soon. ABT is already showing us what the motor is capable of taking the Audi S8 from the stock 512 horsepower up to 612 horses for a gain of 100 horses. ABT does not state exactly what goes into this performance upgrade but we expect a tune, exhaust, and intake modifications. There is no dynograph and there are no performance comparison numbers to support the claimed power increase. Since it is ABT we do not doubt the claim but would like to see real support. Some European tuners just seem to expect us to take their word for it.
