Another update as I am trying some new things and wanted to share the info. I have started to use Racer IQ to log and compare runs so I have even more numbers to digest.
A trip out to the track in May of this year was not a lot of fun due to lack of traction. A 12.85 at 109 was my best of 10 runs that day. DA was 2100 ft. Comparing corrected ETs however the corrected 12.85 from this May (12.537) actually nearly equals the corrected 12.68 (12.532) from last November. No changes in the car since the last time out in November.
In June I strapped on a set of drag radials (M&H 275/45/18). I had some drama with the wheel width and the M&Hs and that is detailed here should you want read about it.

Made 6 runs that day with a best of 12.75 at 110 (12.75/110, 12.80/109, 12.79/110, 12.81/109, 12.81/109, 12/84/110). DA was about 2200 ft. The 12.75 corrects to a 12.42, which makes it my fastest “corrected” time by a tenth.
Traction not an issue as the tires did their job. Again please note the date and times are not right on the time slips. Don’t know why.
Just got the car back from Livernois after a gear change (3.15 to a 3.77) C&L Cold Air and a revised custom dyno tune. Picked up about 18 hp. Looking forward to getting back out to the track to see how the changes work.
[FONT="]Again thanks to everyone here (and in the tire forum) for their help and opinions.[/FONT]
Sounds like there will be some nice ETs coming soon!
Am I reading this correctly that you're running stock suspension, with just DRs for traction?
That's correct. Drag radials on stock suspension.
Few things that I do (and most stock converter guys) would do different. First and foremost, with the stock converter leave at idle. The stock converter flashes at idle. Steeping up the revs will not make the car quicker, and can actually make it slower. Second thing (which you said yourself) was the gear change. These autos run best with stock 3:15's or 3:31's, anything more makes the car shift into forth and lose momentum. Also surprised you need drag radials. May be do to how you load the car, but I leave at idle and get no wheelspin. My track does have good prep though. Not criticizing at all, just giving my opinion on my experiences. For comparison, I just have a Mike Rousch tune and axle back. On street tires, at full weight (even a jack and spare), with my 6' 2" 250+ pound ass in it, in decent 500' DA I run 12.60's @ 111+ consistently. I am doing an off road H pipe and re-tune next that should put me around 12.3/12.2 @ 113/114. Good write up!
Awesome man!!! I imagine you're going to stay with your stock converter now that you have the TVS blower?
How do you turn it off?
Nevermind for some reason I read that as turn off the torque convertor lockup....not sure if serious...but there's a traction control button next to the hazard button where the shifter is.
hold down for 6 seconds while braking to turn off advancetrac
