I did the mod this afternoon. Exactly as you said BlackLS, easy access and only took 10 mins which included me looking for the socket set.
I didn't reset the
ecu yet, wanted to assess any diference.
Well.... it has a little more all over esp mid range where I drive it most of the time. Also seems to have a little more urgency above 5500 RPM so 6300 is a useful maximum now insted of 5800 before.
Bottom end didnt seem to change at all, then I didn't reset the
ecu which makes sense.
I have a full day of driving tomorrow, should things change I'll report back.
