Ill have to go back and look but im pretty sure we installed close to 25 1054 converters last year in trucks ranging from stock vvt to vvt twins to trucks with twins, injectors, lifted with bigger tires...not evwn all of them had tonys tuning. Most of them tow, all of them horse around on the street. I think thats a pretty good variety of setups.

Unless your setup it exactly right, you will hate the 1054 on the street. Suncoast has much better options for DD.

With twins the 54 was awesome compared to the 57. When I took the twins off the 54 sucked towing. Way to tight when towing heavy trying to get that sweet spot. An ML went in and solved the issue. One of these days I'll try an MLG in my personal truck.

Thanks for the replys guys! Looking at the specs, It looks like a 1054 would be a little looser than the 5star I have now? is this correct? It's tough to find much info on the 5star but it looks like the stall speed is around 1700?

The 5star is quite a bit tighter in stall speed but honestly daily drove quite well and 60ft well on Evan's trucks. Both a modded lb7 and a lbz so it really goes back to preference, tuning, and how you drive.

I actually love how my truck drives with my 5 star. I like a tight converter. It seems like it gets the power to the ground well. (For example, driving through a chisel plowed field doesn't take much rpm to move. Same with moving a heavy trailer.). I have no trouble spoiling my s366 with it.

BUT this is the only converter I've ever had. Which suncoast, Precision, or Gorend would be similar performance wise? 1057?

I'm not trying to hijack this from the op but I'm curious and if he likes the way his truck drives it may give him more options.

I think my truck drives "ok" but I'm like you. I don't have much to compare to. Main reason I'm looking to replace is the rattling. I could pay to ship it to ATS then Pay $600 to have them go through it,then pay to ship it back. And I would be crossing my fingers it wouldn't start rattling again.
