Well, Here's the progress, or lack of, after the LT's(w/full exhaust), Double adjustable LCA's, New Hal rears set at 6, and tweaking the AFR in PE mode for 4400-6000rpm. (running right at 12.7-12.6)

I wonder what I'd have done if I could have gotten some traction. Looks like the changes really helped the mph.The track got pretty greasy after the first few runs yesterday, seemed like everyone was saying they couldn't get any traction after about the first hour.

stock 95Z LT1 A4 4.10's

 

Boy that's a great improvement in ET and MPH and all with crappy 60s. Get that to hook and you'll be bottom 13s easy.

 

It looks like you picked up about 3 tenths and 3 and a half mph with about the same 60ft. It will be interesting to see what happens when you get it to hook.

The only changes you made under the hood are long tubes and adjusting the FPR ?

 

Long Tubes and adjusting the PCM in PE mode. It still has the stock regulator on it. I went into the computer and took out some fuel in the PE table.

 

Nice improvement. A converter and some good tires and you'll be the lower half of 13s easy.
