Sure, no problem.

Best times:

12.253 @ 115.67 - bone stock, on OEM tires.

12.078 @ 113.78 - "tuned" on drag radials. Ran this one time and could not repeat it, best average times were 12.1x

Noticed the drop in MPH. The better ET is 100% attributed to a better 60' time: 1.732 vs. 1.871

Trying out Eurocharge with a before and after Dyno hopefully this week if the tool is available.

Did you ever get the dyno runs?

Pulley v8

I got the tune. Got the pulley but didn't put in yet. Is it hard and did someone do it for you ?

Hope to do it next week. Gene
I used EUROCHARGED for tune.
