well i lean the hard way about TCI sounds like to me the stator went out of the stall you will need more stall in a light car and a big cam you will need more stall more gear more stall any thing that will hurt the engine making TQ will need more stall. the best thing to do is give them your cam numbers carb size rear gear tires size and weight of the car and see what they tell you for a stall less is better but if you do not have enough stall you will have to drive it with to feet .i just do not use TCI any more
