Final test and tune at Gateway Motorsports Park tonight

Is your car PP or not? Advance-trac/traction all the way off when you launch? Do you break boost? If so, what RPM? Thats a pretty nice 60'

Yes, it is a performance pack. I only turn off traction control because wheel hop hasn't been an issue before. Makes me wonder if it would've helped me more turning advance trac off also because it lit up on the dash around 100mph each pass. Yes, this was a break boost launch btw

Shoulda read the signature for the PP question... DOH! What RPM are you launching at? I know all cars are different, just trying to see if it is drastically different than my launch.

I can't help but wonder if the wheel hop and advance trac cost me a tenth or two?  I kept dropping tire pressure hoping it would help but didn't unfortunately

As other have said, Advance-Trac, even off, gets pissed when you go fast. I had the same thing AJP mentioned happened ~3 times at the track the last time I went, but a quick key-cycle set everything straight. No actual codes, etc.

I have yet to get wheel hop, I wonder if the H&Rs spring rate was a contributing factor there?

Yeah, nothing lit up on my dash at launch or on the 1-2 shift it wasn't until 100ish that advance trac kicked in. It probably didn't help I was spinning the tires after the water box before staging either. I doubt it was my springs because it hasn't wheel hoped on previous trips with the springs installed

Yeah I have never had wheel hop either, stock springs on mine. I had the car fall flat on its face off the line though. Seems like it happens if you hold the brake boost too long... like ajp said, the computer doesn't like to see brake and gas at the same time..
