Put the SXX SS back in the car, will wait for the version 2 of the SS.

Just wondering, what did your motor temp out at using the new speedo? Did you try to raise the boost or play with motor timing at all. I'm thinking if you started with the stock settings (which are geared for mod) was the problem.
One thing I do like is that the boost can be turned off for SPEC racing and the blue led light will blink to let tech know it's in SPEC mode.
