What you could try is getting a electric exhaust cut out(or manual) So with ease you can have a wide open downpipe. Your turbo's should defiantly spool much faster with much less back pressure from the exhaust. I don't know if you'd need a tune again though, that's what I would like to know. Your only reducing back pressure but running the same boost, so would you need to tune for that?

I got my AFRs tuned good for any psi up to 21 psi, so I think I would be okay, but someone else would need to tune or check the AFRs if they start boosting more than ever in the past, or turn down the boost back to the same psi as before, but if they push more air volume at the same psi then you would need to have a wideband to check the AFRs and add some fuel if needed.
