Default 13.5 @ 104 MPH stock

Took her to the track yesterday. Best pass was 13.5 @ 104.2 with a 2.05 60' time (foot braking to flash converter). Worst pass was 13.7 without foot braking. MPH jumped around on all passes between 102-104 depending on if it would shift at the traps. Most passes she'd shift as I was entering traps resulting in the 102 MPH passes. 2 passes, It held the gear and I ended up at 104.

I've gotta think that there's 1-2 tenths just in trans programming (shifts seem to take a long time even in sport mode).

What RPM were you braking to?

Yeah I'd like to know too, I have a friend who couldn't foot brake it past 1500rpm (seemed to be limited) when he tried to launch..

shoot, I don't remember exactly. I know it wasn't nuts, I'm guessin 1500-1800 RPM or so. Next time I go I'll make some notes.

also, I didn't try the manual shift, prolly would have been able to keep it in gear to consistently hit the 104 mph mark thru the traps.

The trans shifting has been one of my pet peeves w/ this car as well. VMS has a TCM tune offer though that I'm lookin into to fix the "granny" shifts! I have only been able to stall up to 1500 before the tires try to spin.


Good #'s, I'm taking mine out to the track tonight so I'll have some #'s as well.
