How would the .9 spool (thats what is on that turbo for sale on here)? justin tuned my truck in his shop and on a drive around so I loved it. We put his tunes on my dads truck and it runs a heck of a lot better.
The .9 housing is typically recommended for manuals. I have the 1.10 (automatic) and it is okay, but I would like to see how a little tighter housing will do. They have a 1.0 as well so you could split the difference. If you tow often you may be happier with a little tighter housing.
I want to switch to 200% nozzles before I change housings though.
As far as tuning goes I would switch to gear head. He has tuned my truck and with no live tuning he kept my pmr motor alive and he has tuned my built motor and I couldn't be happier with how it drives
