Holley/Demon Carb stumble
Iād like to see what the tac is doing on a couple of runs too.
How high do you load the motor before launching?
My gut feeling is the long seat timing of the hyd cam is having a pretty noticeable impact on low speed grunt with that 6600ā elevation.
I bet at a track under 1000-1200ā or so, it would seem like a totally different car.
