I have had a total of three problems since I installed the supercharger.
#1 - shorted engine harness ECU power to starter relay. This was my screw up, I ran the engine harness that goes over the valve cover directly under the supercharger bypass valve arm. The arm anded up chafing through the harnes and shorting those two wires. I rerouted it further away from the bypass actuator after repairing the wires and no problems.
#2 - stuck bypass valve. My valve would stay open and not make any boost. Started after about three months. Fixed by applying machine oil to the actuator arm bearings once a week for three weeks, problem gone now.
#3 - randomly lost power to my fuel injectors. This one sucked since it left my car stranded three times. Problem ended up being a loose EFI fuse, don't know how it happened and completely unrelated to the supercharger. Fixed by using a tiny screwdriver to bend the prongs of the fuse holder closer together for better contact.
You will need to rewire the Blitz harness as well, FYI.

No time slip yet, I just got tuned with larger injectors last week.
See my post on fuel upgrades, I wouldn't run on the track on stock, the top end leans out to a dangerous level for prolonged periods

It won't make you more power but will allow for a safe 11.6 A/F ratio across the entire power band.
Hoping to get a time slip this Friday. No cooling issues, the Greddy S/C is self-contained for oil so there is no tapping into the engine oil supply so no heat dump into the engine. I did go with one step colder spark plugs to be on the safe side.
Only current issue is the supercharger belt squealing a bit on startup before the engine gets warm.
