So yesteday I drove from clarksville, tn all the way to Steele, Al to Alabama International Raceway to link up with my tuner to do some adjusting of the tranny controller's shift points and adjust the tune some for A/F.

We had made several passes for baselines and the my tuner went to work on the files. So he told me it was ready for me to start driving, and let him know how its performing and etc and what needs improvements.

MY previous best 11.4@117, 11.6@122 before port after was 11.5@116 on Nitto's 555r set to 18 psi ( 305/45/18)

only change was I ADDED stock gt500 axle backs to my pypes Mid- Muffler system so basically running 4 mufflers due to sound with the X-pipe, and 15x10 racestars with 275/50/15

so i did the following 3 runs with about 45 min in between for cool down

DA:2748
temp:89
hum: 100%

Tire PSI went: 18-16-14

--------1st-----------2nd-----------3rd----------
60'........ 1.683-------- 1.768------ 1.651
330....... 4.893-------- 4.931------- 4.720
1/8........ 7.552-------- 7.521------ 7.252
MPH...... 91.49-------- 94.21------ 96.33
1/4........ 11.835------- 11.674------- 11.317
MPH...... 117.64------- 121.27------- 123.67

I ran outta time and to get close down to start my drive back home, but We get the tune were we want it for A/F 10.9- then goes to 11.5, the shifting for the Auto Tranny could have used about 2 more passes As we were adjusting everything for the top end as that seemed to be were the issues were

Well i wontbe hitting the track any time soon again as I dont have the flip switch installed yeet so that race tune for the tranny is on his computer. So when the car goes back to him for the research on the A/C problem after the swap to get fixed itll go in so i can have a track shift tune.

any way im glad atleast i did a PB in that hot weather

2005 gt500 swapped rocking a 4r70w your typical bolt ons port and pulled 11.43@117..

also.... ive posted all this here before tho not new around the parts.. LOL

Here was the first run We coudlnt get the controller to get it to go into D-1 so it started in 2nd gear Hence why it sound like he bogs off the line like maunal's do.. 12.6@119 i think it was but it was the first base run to get the readings.
