I just swapped out my SC 1057 for a SC 1056, now my truck feels like a stone???? Do these two converters differ that much? Should I have my tuner adjust the tune for the new converter?

describe "feels like a stone"... The 1057 is a really fun converter the 1056 is not... but they both get the job done.

i belive the 1056 locks up faster, so mabye your just having a harder time builting boost off the line... why the switch though, didnt like the 57?

I belive it is because the 1057 couples sooner. But then agina I don't know much about these things.

Yeah the 1057 does couple sooner and the 1057 locks up faster than the 1056, 57 stalls at 1700-1800rpm and the 56 is 2000rpm, I would have thought the 56 would have felt faster off the line being that it stalls higher.

Usually looser converters feel slower untill you mash get into it pretty hard because there is more slippage.

My 1056 was pretty loose also to the point where when it locked up it would blow the tires away.

kyle has a fix for this... while you're ordering his mild steel innovations you can get the stop converter creep mod of his...

Ok, I think I'm going crazy. Doe the TCM have to relearn after changing the converter? Now my truck feels like its getting better???? I launched it pretty hard last night on the street and it smoldered the front tire too!!!!! Never did that before.
