Dont know much about converters so here it goes.......
Is there any performance difference between a tight stall and a loose stall?

 

Yes, one that is considered tight will have a higher multiplier (STR). This will increase the amount of torque applied to the tires. However, typically, the higher STR will be less effecient in the upper rpms.

So when comparing two exactly the same stall speeds with different STRs, traction provided, the higher STR will cut a better 60' time, but the lower STR will be more effecient overall.

See Yanks web site for a graph.

 

so the more loose the converter is the better? The reason i ask is because i currently have a 3000 stall and it feels kind of loose, and it gets pretty annoying while driving around, i have to punch the gas a lot in order for it to move. A friend of mine has a 3000 pi and his truck feels like it has an original stall until hi punches it.

 

dont trick yourself into thinking you have a strong top end camaro. get the 60' down and the times will be best. thats the trick with trucks IMO. get it outa the hole strong and keep the power decently low/mid.
