A looser converter will definately make the trans feel different, especially when the boost comes up with a looser converter. Most of the time you wont even see the tach move and will just feel a slight bump. You feel a lot more of the engine pulling and the shift firmness with a lower stall speed especially during in town driving. Going from 3.69s down to 3.29s is a pretty good jump also and Im sure that is half of what you arent used to yet and a looser converter on top of it probably makes the car a bit lazy in town compared to your old setup
