Today, admittedly was my first time at the track as a driver.
First pass, Me vs Subaru WRX.
[TC off.] Red light at start!

Second pass, Me vs the fastest car for the day and his slowest run, a blown '71 240Z
[TC on]
Third pass, Me vs GT-R
[TC off,] but car didn't shift and hit rev limiter

I had enough. Was just tired but a run an hour down the 1/4 mile. On way home, transmission got goofy on me. Popped outta gear, wouldn't go into gear. Wouldn't shift. Engine off, engine on, seemed to clear it up, but it repeated badly.
Checked car with tuner, realized I was running stage 4 and NOT 4+! I wondered why my times were so far off from I was seeing from my OBD2 connector. But transmission error P0096. Aww hell! Car really sick now. So I dropped ole girl at the dealer to check!
Will go back with the right tune loaded, and hopefully a better performing transmission. I guess I should pick up at least .2 seconds with the 4+ tune loaded. But anyone in So Cal that frequents Irwindale, consider the FOntana track. Run the whole 1/4. Some VERY stiff competition.
