tried a lot of things but could not get rid of this jerky action
i have attached datalog where u can see accelerator pedal is steady and throttle is jumping up and down, so car is getting jerky same time.
at that moment there is no boost, engine is still in vacuum area and throttle is not opened that much.
doe anybody have any pointers with this issue?
attached log with file.
p.s car is running Procharger, upgraded MAP and injectors.
thanks in advance
