My first time using the Garmin Catalyst - dropped about 3.5 sec off my prior personal best (some was also due to the intercooler, RSB, and trans tune).
Vehicle specs:
2019 VW GTI Rabbit Edition DSG 7-spd (Performance Pack standard)
Drivetrain: DO88 IC, APR trans tune (still stock ECU tune for now), 034 torque mount inserts
Suspension: 034 Camber plates, H&R 26mm RSB
Wheels/tires: Apex 17x9 SM10s w/ 245/40R17 Falken RT660s (which are DONE after a full season on them)
Brakes: Ferodo DS3.12 front pads, DS1.11 rear pads, Zimmerman blank OE style rotors all around, RS3 brake deflectors, Motul RBF600 fluid
Misc: Apex wheel stud kit, VCDS tweaks that most everyone does. Increased traction on the diff, XDS set to weak, straight ahead brake stabilization turned off and probably something else I'm forgetting.
