Mark,, I'll talk to Stefan a little more and see what's u.
I don't know what the DD turbo is,, But I know it's not a '40
It's supposed to be able to make a little more boost, and do it a little cooler than the B-1, it also comes with a Downpipe for about the same price of a B-1.
I was gonna drop the Big Kahuna's on a B-1 along with BD-5's, Pusher pump, more gauges etc.
I like KWIKKURT, and his turbo is good,, but as competition goes,, someone has to make a little better product. (Chevy D-Max 300HP,, '03 Cummins H. O. 305 HP) Isn't that how the world turns.
I'm calling Stefan and see what's up,, get some hard facts. LOL, I don't even know if Anybody is supposed to know about this turbo

Stefan said I would get the first run of turbo's, his 1st, then mine.
I'l post back and put up some knowledge I will learn. (Everytime I call Stefan He teaches me something, LOL)
