How much are these 6. 7 stock clutches holding when you start adding power to them. I would like add programmer or chip down the road and was wondering how far we are able to go with the stock clutch. For example what levels are you guys with the Edge/Juice getting buy with. I would love to have a smarty JR for one of these trucks but I guess there would have to be a smarty before a smarty JR huh!!!!!! :-laf
