Can the 1057 be sent back and changed to a 1055.
No.
Different converter. You are better off selling yours and buying the 1055.
i know you said the 1057 can no be changed into the 1055 , is the 1054 in the same boat or can it be changed to the 1055 or something looser? i have gained alot by tuning but it is still just too tight to let my turbo spool, after wot it probably takes 4-5 secs to get things rolling and thats smoking like a freight train, also with lower tunes , stock tune prob takes 6-7 secs to get it spooled ( my times are gestimates i can stop watch it if nec ) how can i test the stall speed to see were i'm at . by the way i love the cooler , trans went from 195 - 200 to 170 - 180 , well worth the money !
I don't see how the 1054 is too tight for a small turbo like that. the BD is an S300 turbo. I run a 4094 with a 1057 and it lights fine. I doubt your problem is lying within the converter
have you ever ran a 54 ? why would it be that same tune before 54 was fine and after trans build it would not spool up , since then i have moddified every tune i have to help the issue but i know what my truck is doing and what it isnt, and maybe the particuler 54 i got is to tight that is why i was asking how to check the stall speed ?
The 1054 is very close to the 1057. The 1057 stall is 1800 rpm. Give MikeL a call he will have you answer.
thanks for the info , sorry if my post sounded short i was in a hurry typing and after reading back it didnt quite come out right , i was going to call mike but i figured if i posted it would be info others could veiw and might be useful , either for choosing a converter or diagnosing a problem if i find out one exsist, also i'm getting ready to have htt upgrade the s300 to there 71mm with a stainless housing but i have been hesitant with the spooling problems i am having with this small of a turbo were is a sheep hearder when ya need one :bow:
Who wants a 1055??? May know a guy willing to trade a 1055 for a 1057 or 1058. Let me know ASAP!

Pat tried this charger at the track on Saturday. Spooled the charger 13% bigger then GT42 with no problem he was cutting 1.56 60ft times iirc.
Here is video of the launch :rockon:

Sorry about the OT Kat, but where can i find vids of you guys racing? What was the outcome of Pat and that dodge?
I'd say you're fogging the motor out. There's a point where you have so much fuel it prolongs spoolup. Take some fuel out of the bottom end and I guarantee it will be faster.
