so i have a heads cam ls6 with 4.11's and a th400. feels like a dog.
car isn't fully tuned however. i was wondering if switching to a very tight stall will make a big difference... current stall is extremely loose

 

wow no one?

 

well switching to a tighter stall will make the car feel tighter in the bottom i dont know about faster. generally high/loose stall equals better launch . Tighter lower stall equals better low speed feel with a sacrafice of full throttle launch feel .
