Is this True about converters??

When dynamic did my convertor I sent them my dyno sheet. They sent me a convertor.

What i'm saying is that buying one of those name brand, off the shelf, advertised stall speed convertors probably isn't going to function well. IT may not fail, but it may surely dissapoint.

My dynamic was a 3900-4100 stall speed 9" unit. You'd never know it was aything but stock until you mashed it to the floor.

Current convertor is an art car 3500 stall convertor. It stalls at 3400 and again, acts bone stock.
