Marco,

The setting of the stop is not going to be the issue with the tree. You need to really focus on how the car is pulling itself out of the beams. If it's just rolling out of the beams and not picking up the tire then your lights will struggle. The best thing to do is have someone video tape the car next time you are at the track to see what it is doing. There are many factors to adjust to get the car to react, four-link setting, starting line rpm's, how you stage...etc. Hope this helps out but, these are some factors that we struggled with our car hitting the pro-tree.

Thanks for the info. my converter flashes to 6400 so I have a 5600 leave chip should i go up or down? I have weight in the nose about 25 lbs should I consider taking it out? I bracket stage for consistancy. My car is a dragster that runs easy 7.30s I cnn't believe that I am even having this discussion.

Any chance the car has front end stagger? If it was built for comp, it probably does....

We leave the line at 6200 - 6300 on the converter but, the car is 2,600 hundred pounds. Maybe look at taking the weight out of the front or even putting a lesser amount and even taking a look at the size of the front tires and how much air you are putting in them. There are tons of options to look at but, whatever you do write down what you do and don't change a ton at once. Seen too many guys change 20 things and then can't get back to what orginally worked...lol

First how much delay do you carry when bracket racing on a full .500 tree?
Are you consistent on a bracket tree?
Are you new to a pro tree?
Do you use an SLE?
Most of the time an experienced bracket racer will struggle a little at first when going to a pro tree. My questions are to determine if its the car or you that is the problem. I had trouble squeezing the button on a pro tree because of decking the motor while on the button. This just rattled me for a while but eventually got over it. Your timer setting of .100 is average for a dragster. I know some who shut it down at .050 or less. In my opinion you want to drive out of the beams with a dragster to be more consistant. With a car as fast as yours it should not be a problem.

Really need more info to help.....

You say struggling...everyone considers struggling something different... by struggling do you mean you can't get out of the .015 teen style lights? Or you are stuck worse? 20's 30's 40's?

Which tire do you have on the rear of the car? 4 link? monoshock?

Which button are you using? And is it set up for shortest throw?
