I'm getting the 1056 but won't have my truck back till later this week. It's suppose to be a good all around convertor.

I've read the 1056 is a good all around tc and the 1058 is good with larger singles and twins.

I have a 1056 behind my LML and a 1058 behind my LBZ.... You can't go wrong with Suncoast, I absolutely love my converter!

I custom tune all kinds of stuff and try to make them go faster, breath better, and play nice.
When in doubt, 0xFFF it out

A few rigs in the trough... Couple fords, duramaxes, and a little ecodiesel with a lot of heart!

Thanks for the info guys I think the 1056 is the TC for me.. I think a 66 or 68mm turbo with work good with it. Does suncoast have a warranty with there converters?
