Ronny's timing table helps me drop 1/2 second.

I've been meaning to post for weeks but am short on time. I finally made it out to the track with the bird. First time I went out, the car really fell on it's face out off the line and best I got was a 15.1 @ 95.1. Really disappoining.

Anyway, to keep it short I grabbed the data and tried maiking some changes to the original EBL timing table that I have been messing with since tune 1. I am on 90+ right now. So, I drove a bit and it felt worse. Then I figured that it would not hurt to just try Ronny's since I have a somewhat similar build; that being an aluminum headed 350, 2" tbi and kind of similar cams. Best run is below:

R/T .970 Got to get launch tuning and clutch feathering better
60' 2.386
330' 6.376
1/8 9.597 @ ? right lane mph broke
1/4 14.665 @ 99.67 MPH is showing I shoudl be quicker.

Never made it out of 3rd gear with the t-56 and 3.42s. I am hoping for 13s with tires, gears and proper tune. I'll get the datalog for the run online this week.

Thanks to all for the help esp Rbob and Ronny.
