I install two days ago a Booster Plug-Denmark on my 2017 RS; simple and intuitive plug and play gadget, no "check engine". First day I've noticed a smoothness at on/off throttle , some fuller acceleration, seems little less vibrations over 2500 rpm. Next day... it seems not anymore quite the same, I feel vibrations again and behave not so smooth at accel/decel; all test are in urban conditions. Is somebody here who install/use this gadget and knows more tips & tricks about how to proceed more effectively to make the ECU learn/understand the new way of reading more efficiently, apart from those presented in the manual?
