It's still only 2 stages of compression with triples, same as twins. The difference being, you can spool 2 smaller primaries (maybe a pair or 66mm's or 71mm's etc) alot easier than one big one (S480 or S510 etc) and still flow plenty of lbs/min.
Not a Ford fan by any stretch of the imagination but when you can do tuner, intake, exhaust and make 550+HP on a stock trans it gets my attention. All the ones I've been around so far have been trouble free, tow like crazy and fry 35 inch tires like it's their job. I would buy the Ford before...
Finally got the two videos of Trent off my camera. Not sure how to embed them but here are the youtube links.

AFAIK they modify stock harnesses. Either you send yours in and they change it or they buy a brand new one from GM, change it, then bill you for the new harness. At least that's what I was told when I called about a year ago. Maybe they're doing them different now. :dontknow:
One of the best posts I've ever seen on a diesel forum. Everyone should at least think about some of the points in it before posting something negative or just plain asinine.
