When the tech drained the Rotrex filter into a container it was completely obvious the fluid was full of metal remnants.
So I am weighing replacing the supercharger versus returning the car back to stock. Sorry guys but going another FI route is not in the cards for me right now. I am a little leery going the replacement route as the original lasted 34 months and 27k miles with no track time and no auto-x. This car was only street driven and it is my DD.

OK -81 is stage 1 and 1.5. You need the GTM kit to upgrade
-91 is stage 2 only
Next you can get a new unit from other non GTM source for $1800.
Last I think your unit may be under warranty contact rotrex direct to find out.
PM me if you want more data
