Upgraded from the S3 short shifter to the Diesel Geek Sigma.
Not sure how I feel about it yet. Very notchy, and now that everything is tightened up it almost sounds like my knob is loose. 3rd to 2nd you have to be kind of aggressive with it, almost feels like rev hang. Might need a readjustment.
Swapped out the old plugs. ~12,000 miles still gapped at 0.024" with most of the mileage from the JB4 before going over to Cobb.
On top of my battery leaking acid, which VW does not want to warranty, I also found my ground strap cut up somehow.
