Sigh, had a long response typed and got wiped out...we'll try this again...!
Thanks for taking the time to do the writeup, i'm also in a ZF6 truck and it sounds like this is working out really well. i'm waiting on KC to get some parts and buy a complete turbo, hopefully these come in soon as it sounds like this will be a GREAT upgrade.
one of my biggest peeves with the ZF6 is loosing boost between shifts, I run a turbosmart blowoff valve which actually helps a lot with this. it sounds like with KC tweeks i should have a turbo that is extremely responsive between shifts.
