Full bolt ons = headers, ORY, exhaust, CAI, RR's, LCA's, TA, 58mm TB, free mods, drag tires like Nittos/slicks, gears, stuff like that.

I wanted to see where the power is peaking, what kind of torque you have from 2500+ rpm, what the a/f is (not necessarily to see if it's rich or lean, but to see if it's where the LT1 likes to be for maximum power), this 5k miss you have, etc.

The LE2 setup has 2000 miles on it. The miss I've had for the past 50 miles or so.

Ill do some digging.

Also, a friend who has the same setup as me, the one where we installed these setups back to back... well, he out 60 footed me, and only beat me in the 1/4 by .002 seconds. I thinks thats good considering he has a 9" and is launching hard, whereas me in the 10 bolt had to ease it out of the hole. I was beating him in the 1/8, and he beat me at higher speeds. Im blaming this on the miss.

Did you ever get the cam degree issues fixed?? I was looking forward to seeing the car at the track that day but sh*t happens i guess.

No, never degreed the cam yet. Im thinking about doing that over the winter, but with it Im going to need another tune, in the tune of $450 that is. Thats why Im holding off for right now.

We were under the impression that degreeing the cam was not necessary, but obviously we were wrong. We'll see what happens.

What cam degree issues are you having?? Degreeing the cam is just to make sure that all of the specs are the right ones and nothing is way out of the ordinary. Why are you paying $450 for a tune? The most expensive guy around here is like $350 and that is for wideband tuning and everything. Hopefully you get everything worked out and get the car going like it should be.

Well, the cam was installed properly, just not checked if we needed to degree it.

$450 is what the guy around here charges, and he's the best. www.flp2win.com

Re: 12.64 @ 111.88 with the LE2 today.

^^ I did that once. Not quite that severe though. I only broke a couple of teeth off of the ring gear. Make sure you take your posi-unit apart and clean it good. Also, setting them up a tad on the tight side of the recommended back lash will help also. It may make a little noise, but I've seen them last longer.

Re: 12.64 @ 111.88 with the LE2 today.

This setup was set very tight. I forgot what backlash I set it to, but I know it was much tighter than what the speed shop set it up at.

And, when I set it up myself, it made absolutely no noise as well.

For the time being, Im throwing in there a Torsen w/3.73's that I bought for $90 from a friend. An then in the spring it will be time for a 9".
