Bad stall = low dyno #'s? Situation: I had a stall and small cam put in and had it tuned and it made good numbers and ran perfect. A few months later I had 3.73's put in ran it at the track and with a better 60' I went .01 slower, consistently. 
The car felt fine so I really couldn't figure it out. Well I decided to go with a bigger cam and get it retuned. Well when we did the car made less rwhp than it did when it had bolt-ons. 
The car seemed fine, so the only thing we came up with was low cylinder pressure, which we didn't get to check yet. Well last week the car was acting really weired, you would have to floor the car to get it to move at all. We took it back to the shop and it turns out the torque converter was bad. They said there was so much build up in it.
So we are getting a new converter.
My question is would a bad stall or a stall that is going bad cause the car to dyno low?
