@805moparkid:
Thanks, agree on the 5000 or 5500 launch, that is what I did with SS springs and it was fine, but this is what Mr. Calvert told me to do after nothing else worked, and it worked the best.Doesn't matter any way on a full tree, one can drive out of the lights.
If I do that, I launch perfect, then it goes out and unloads the tires.
It's not squirly. The 330' and 1000' number losses are minimal, it's the 60's that are the most off.Can be as much as a10th.Depends what mood it is in.And it may make 2-3 consistant passes, then fall off or pickup.
Fuel system is fine, was on the dyno earlier this year.It's when I changed to the springs/ bars that this all started.
What rear springs and shocks are you running? You have a lot of rear seperation.
How much front travel do you have from ride height?
Thanks Chris
