>>I ordered the Hoppen Stage 1 upgrade from Keith Anderson. His service was top notch and he returned the ECU very quickly. With the upgraded ECU there is a very noticible improvement in acceleration in all gears! My S6 is even more of a pleasure to drive than before. Speaking quantitatively, I measured boost pressures of around 1.1 kg/cm^2 with my OEM ECU. With the Stage 1 ECU, boost pressures were generally around 1.3. The highest I have read in testing so far is 1.35. Sometimes I have only managed 1.2, but the conditions of the experiments are never the same. <<
