Sounds like you are going in the right direction ! .04 gain in the 60 is very good !

OK
After a big week end at Steel in Motion I have news to report
I have discovered my car LOVES to leave from idle
I sort of found the cure for everything
I am at 8 lbs on my MT 33x10.5's--leaving from idle Vs. raising the RPM has calmed all the ills right down
It made two fantastic passes --track was great and it was Rocking down through there!
Car hooked smooth and launched straight as a bullet everytime leaving from dead idle , footbraking
I have finally found what it likes so all the tire pressure ups and downs and spinning / not spinning etc seems mostly to have been about the track prep or lack of
On a good tight track car has always been good but this wk end I think I found the key
Yahoo!!!

Hey Duster Dave, how about some ET & MPH numbers????  Glad to hear it's sorted out.....

I also added another 8 lbs to the front for total of 40 lbs
It really seemed to Make the combo
I will admit that at the Show yesterday there were no clocks just flag and go but I was able to tell none the less--It is Working like a car should now!
Added weight, leave from idle, wheelie bar about 3 inch ( no higher) tires 8-  8 1/2 range and
Away we go! Car smooth as a new jar of Skippy!
Seems like everything got better with leave from idle--I had left as high as 4000 range--mostly around 2500  It would leave hard as $%&# but was too violent at the hit just upsetting everything
Now...I really feel like I have a handle on it

I feel ready for the season now!
One note--it has never bounced at all during shut down and it did this week end--don't know if it is the lower tire pressure ( lowest I have run) or maybe was track surface--I am usually like Gladiator and tour the top end like checking out the dirt where I am going to fight but this is the ONE time I did not check out top end and it was some hard bounching down there--I think it was the track and maybe I got on the binders a little too hard too fast --That was No fun at all--I got back on it for one second and then eased on the brakes and was able to calm it down--Bounced my helmet off the cage a time or two--
I keep learning this thing, maybe by about Sept I will have a real handle on it all.
