How's the Z going? My advice is to get atleast one EGT gauge (probe on the driver side)..It's very useful when dyno tuning. Go with the Greddy warning/peak hold EGT. You can also use the external warning wire of the Greddy EGT to shut off the boost controller when exhaust temp reach certain preset point.
Also, go with the hks2530 instead of the sport 600. More power:)
Hope to meet you again if I'm stuck in Naple next time :)
