Ok - getting ready to recieve upgraded transmission TC VB shafts and plate. Currently running TSTPMCR (old w/o guages). A few years ago a pressure box seemed to work well with it (I think the EZ was most common back then) I do have 35's on now and didn't realize how much I would lose with them on the low end 
My questions to you all:
1. Are there any newer pressure boxes were available that seems to work well with the TST or is the EZ the way to go
2. I was looking at a smaller turbo like the Auora 2000 (or anything similar) that once I get some fuel upgrades, I could turn into a dual system OR a mid size that will support what fuel I can deliver to it now- Any suggestions?? I am looking for something that has a faster spool than stock and can help with the egt's with the tst and pressure box.
3. Am I upgrading in the right sequence - I cant afford to do it all at once (transmission was a big one) and want to make sure I am taking the correct steps.
Thanks again for any advice!!
