I achieved some of the maintenance items over the winter and kicked some down the road a bit. I did dyno the car this spring, 322 whp 311 torque.
I've had it out on track a few times this year, with no major issues. The way that I had coolant temp spliced from the Audi ECU into the boxster cluster worked, but was not optimal. Being resistance based, it read low on the cluster and the ECU. Not in a problematic way but I wanted to improve it. I added an aftermarket sensor in the coolant pipes from engine to radiators and a gauge for monitoring. It also blocks the Check Engine light!
Have a few more track days this summer/fall that I am looking forward to. Thinking I will add an aftermarket oil temp/pressure gauge in the next offseason.
