Ran my personal best time today. It was the first pass on the year on the track.
Same set up as last year except i had the GTM torque converter on the car.
The quickist 7 AT with bolt ons.

60 ft..... 1.869
330...... 5.351
1/8 ...... 8.185
MPH...... 89.24
1000...... 10.634
1/4...... 12.721
MPH...... 110.05

Temp was 52 degress and the tracton was good. Launched at 1900 to 2000 rpm.
I will have the skinney front tires on next time i go did not have time to pick up the rim today.

will post time slip soon.
I ran the stock fuel curve and stock nissan ecu settings as i have not put new map in with the uprev/
It would hvae gone in the 12.5's but for some reason when i shifted into 5th the rev matching did not work and the rpm dropped to 4000 rpm from my shift piont which was 7200 today. It usally only drop's 1100 rpm. the car lost power during that shift every time.It felt like the motor stalled and then came back to life.
This only started happening after I hooked up the uprev to my car.
Need to know why this is happeniing. It's just like missing a gear. The motor takes time to aclerate after this gear change.
Other than that the car was very quick.
Next time i go i will be putting on the stock manifold taking off the Motordyne and using my cobb for tuning. The shift piont will be 7800 rpm.
The GTM converter worked well.

One happy Z.
