One of our customers with a '99 C5 A4 with 383 LS1 with supercharger and our water/meth injection we custom tuned back in March of 2004 came by and we did a testrun with Ease scanner recording so we could checkup how engine and tune has done over the last three years.

No changes have been made to the car since the tune we did and was nice to see the PCM calibration was still right on.

Fuel trims, timing still just as we set it, no misfire and almost no knock even with the 91 octane gas.

At 3500 feet elevation engine produced 570 ft/lbs torque with 668 flywheel HP
