Default Sti Track Day: The Good, the Bad and the Ugly

Well, I just completed the break-in and took the beastie onto the track for some truly aggressive driving. We went to Spokane Raceway Park, a nice road race course with a couple fast (147MPH/6th gear) straights and slow corners (2nd gear).

The Good:
Wonderful power & torque. The thing just claws out of corners. Great power for out accelerating Porsches & Beemers on the straights. The brakes are solid, with no big issues once race pads (Porterfield R4) and high temp fluid (Super Blue) are fitted.

The Bad:
It needs more camber adjustment! My alignment shop could only get -1 degree in the front and -1.5 in the back (with camber bolts installed). I'd like to get -2 and -1.5.

This isn't too bad, but the brake lines need to be upgraded to steel braided units. The pedal is too soft for easy heel-toe (or in my case, left/right foot pivot).

The Ugly:
I had the engine cut out on me a handful of times while at WOT in 5th gear at around 5k RPM, followed by a CEL. Pulling the code showed code 0244 "Turbocharger Wastegate Solenoid A Range/Performance". So I'm thinking the ECU thinks the boost is too high to control with the Boost Solenoid. Strange, since the only mods are silencer removed and Turbo-back exhaust. The boost gauge showed boost at about 16psi. EGTs at WOT, high RPM were 1560F or so.

No noticeable knock though.

All in all, a great time. But the CEL & engine cut are disturbing.
