these particular lines intrigue me.

"it is apparent that the manner fueling map values are being altered indicates stratified charge combustion is not yet fully understood and in some cases is simply ignored, ie gross over-fueling."

"when the fuel supply pressure is significantly increased without revising the spray pattern of the high pressure injector the s.c. combustion process will be altered.

and your engine will not produce maximum power output because in most modded s.c. engines over fueling will occur at various thottle and rpm values... this is specific to s.c. engines...

yes you have a stratified charge engine having reasonably good tuning potential - but unlike 1.8T, the 2.0TFSi (s.c.) is less forgiving when incorrectly modified."

Plus, I've read somewhere that the north american versions of the 2.0t are not available with stratified charge? What is exactly going on here?



Would like some comments please. Better yet if tuners would like to share their approach on tuning the car for more power yet maintaining FSI functionality. (if it's confidential, I apologise for asking)
