Reaction Time Troubles
Just trying to figure out what might be going Wrong with my Coupe, was usally running a .030 to .040 light off the .500 Pro Tree and the past 4 races cant get better than .200's Tried deep staging , Revving up load Nothing seems to change. Could it be the 2800 stall converter needs a tune up ? Any Ideas or suggestion would be greatly appriciated

Same track as before?
And were you also deep staged before when cutting the .03s and .04s?
You might not be staging in the same spot as before, there is a notable difference in R/Ts from just barely turning off that top bulb and stopping to really bumping into it a bit after you put it out. But even so, a shallow/deep stage to a deep/deep stage generally won't result in that kind of a gap/change, a .03 to a .20 is a lot.
Also weather conditions, were you running in much better air when you cut those .0 lights?
Finally tires, is there a chance that you're spinning a little bit at the launch and just aren't feeling it? The tires could be going away as well.

Now this will be a fun one.
First thing I am going to say is make sure the tree was not changed from .500 to .400 cause that is a tenth right there.
Second, converters will affect your RT but if was going to affect it that much you should be seeing other differences too i think. That is a big difference. Are you sure you are footbraking to the same RPM as before?
Next, did you change tires/wheels? Taller tire will take some RT away though not that much.
Lastly, driver slump?

True, if the converter was going bad his sixty foots and ETs would likely fall off by a noticeable amount as well.

Set up
I'm using the same complete setup and Trying my best to always deep stage with one extra bump in. I even noticed my sixty foot times dropped from 1.60's to high 1.70; even a few 1.80' Tire spin when it happens I do not count them runs in.I have tried leaving from idle and tried leaving at 500 rpm incriments up to 2000 with no difference 
Finally Edgar Ya we are all getting Older 
Always running off the .500 tree
Final attempt might be to go to a 3200 stall , After that I Give Up
My 2800 Vig stall is 4 years old now,might that have anything to do with this ? Lots of runs on it!
Thanks Guys

That sounds like the converter is tired..
After 4 yrs the clutches wear, and the hit isn't as hard..
Not sure if that is affecting your R/T but the consistent drop in 60' is what opens my eyes..
Just make sure its not a drop off in 60' due to the summer..
Many cars run .2-.3 slower in hotter conditions..

Just Getting Tired
Hello Ellis Thanks for the reply this early in the morning Feels like a Never Ending Battle Get one Thing Going Right Something Else Pops up. It has been a Very Tough Summer here with Very High Humidity all season Just Killing all of the times. I know my car has slowed down at least 3 to 4 10/ths in the heat . Last Event track temp was 135 with 100% humidity
Take Care Ellis and Good Luck with the rest of your season

On any pro tree you should be able to make adjustments staging regardless of conditions, converter etc to cut a better light. I know with my car on a 500 pro tree if I turnout the top bulb, I'm going red. shallow stage is a .020 to .030 one bump is a teen and 2 bumps is a .00?. I would never go 2 bumps in competition, i hate giving it away by going red.... now a .400 pro tree is a complete different story....

A TC is like a turbine inside,The only clutch thats in there is for lockup .And there is one or 2 bearings I think inside.The only thing that I can think of to go bad is the bearings.And if you try to lock the TC in the top of 3rd @ WOT,You can wear that clutch out.But that clutch has nothing to do with launching the car.Just my 2 cents

You may want to give Greg Samuels at FTI a call...he is a guru with converters....his prices are reasonable and you will never find better customer service...his converters win so many events nationwide it is stupid silly...
FTI...1-866-726-8358
I have run his converter for 3 years now and could not be happier...the call is free so what have you got to lose...he costs less than Yank and Precision but will build you a custom converter specifically for your application...

Going from .030-.040 to .200 is huge. In the heat of the summer my car's reaction slows the max of .060. Did you make any changes to the car?
On a pro .500 the drivers anticipation is removed from the equation but
from the drivers standpoint are you "sitting" on the amber?
IMO something has changed other than weather to get a jump in RT that much.
Just to restate the were the .030-.040 reactions on a pro .500 tree?

Today at E Town in the "Pro Dial Dash" which is run off a .500 Pro Tree...
My car is an 05 C6 Automatic (A4) with a Stock Converter and 3.15 gears...
I had two qualifying runs.. the first I staged DEEP and went -.013 RED.. on a 500 pro tree.. 2nd qualifier I shallow staged and went .066..
In Eliminations I had a .030 and in the final I won the race via. Reaction Time the other lane had a .014 RT and I had a .003 RT and won it by >< that much... the Reaction Time gets to be really important when you have two experienced drivers....

But now still struggling. Tried going back to the LS6 intake setup Worked a bit better but still not there. New Converter going in soon. It so much more Fun Racing and be competitive , rather than just showing up and rolling Along
You have it So Right with the Reaction Times ... Makes A Ton Of Difference in a Race
Great to see that your winning rounds also
