I know it's NOT the correct figures and I feel once I get the calibrations down I can give closer to real life readings. The intent was to show the before/after figures even with the error factor taken into consideration.
The spread between the numbers is correct............just the numbers are inflated, even though the horsepower readings are very close, the time/speed is whats off.
The gas mileage gain is 100% CORRECT!!!!!!!!!!!
I believe our XF weighs 3060lbs and with gas and my carcass I figured @ 3400 being close enough until I get it weighed.
The company that provides the chip programming is out of Austria and is called SpeedTuningUSA............

Anyone that desires the chip will get the same as I paid, even though I am a previous customer (my Turbo Beetle was done over two years ago) which was $313.95 Installed/Including Tax!!!!!!!!!!!!!!

Just mention this site and me (JD).
