I just installed ATS Diesels new Sub Zero intercooler in my 2wd truck, thought I'd post up my thoughts. I'm really impressed with this I/C, very nice piece, dwarfs the stock unit. Works great too.
Here are some numbers for comparison. Stock I/C is 17" tall and 2" deep. ATS is 26" tall and 3" deep. The ATS cooler also has larger 3 1/2" pipe inlets, it came with all the new boots you'd need along with hose and fittings for re routing the trans cooler lines. The end tanks are huge, and have bracing throughout to keep them from blowing out. Quality looks top knotch. After comparing it with the stocker side by side, I was worried it wouldn't fit. But it did, just had to route the tranny cooler lines around the outside of the core support instead of through the inside. Doesn't look to be rubbing the radiator or a/c condenser anywhere. Only issue I can see is the drivers side i/c pipe doesn't line direct up with the inlet on the cooler. It's kind of crooked, the boot went on just fine, but I'm worried it might blow off, just have to see.
Cruising in Race Tune at 70mph @ 700-degrees EGT's. Rolled into it hard and ran wot up to 95mph, peaked at 1575-1600-degrees. Was just about to peg out the pyro when I let out of it at 100mph.

It definitley works better than the stocker, noticeable difference on the gauge. Overall boost is about the same as well. Pretty happy with the results so far.
