Attention: TDR Forum Junkies I was one of the lucky people to take advantage of the group buy put on by Performance Diesel Warehouse on the Industrial Injection turbos. I called Doug to order an SPS62. He advised me that since my '06 has an automatic transmission, I'd need an HX40 downpipe. Doug was a very pleasant to speak with, and he was very nice through my many questions.
I think a couple of you saw my questions on this board regarding the installation. I think ultimately the few answers created more confusion upon installation. Some say I needed the HX40 downpipe, and others said I would have an 8" gap between the downpipe and the exhaust.
I removed the stock turbo without too much of a problem - those nuts can be a bit difficult, especially the rear, inside nut. I went for broke with my Craftsman 3/8" sockets/extension (the 1/2" swivel wouldn't fit), somewhat expecting to break something to break. Fortunately, nothing broke. I also had to do some grinding on a closed-end wrench to fit the outer nuts.
I considered what was said regarding not needing the HX40 downpipe, but I noticed the exhaust mounting flange on the SPS was only 4" vs. 4-3/8" on the stock elbow. This isn't going to work!
I called PDW and left a message for Doug. I then called Industrial Injection, and the guy there said that if I wanted to use the stock elbow/downpipe, I should have got the "large flange" SPS, not the small flange version. I went on to tell him that I was told that I needed this setup. His reply was that II has been trying to educated their dealers that an HX40 downpipe is not required on '04. 5 and later trucks, and that a large flange SPS should be used.
I hadn't received a call back from PDW, and I was sitting there with my truck halfway out of my garage, and I needed to get the truck back together. I didn't want to reuse the stock turbo, so I started installing the small flange version with the expectation of using HX40 downpipe.
Again, no real problem installing the turbo or the downpipe. The transmission dip stick tube required an adjustment, though.
Somewhat as mentioned, the downpipe was short. Although it may have seemed easy to cut the stock downpipe, it is ovalized in this area, and the downpipe was misaligned by nearly 2 inches. Not a chance a straight piece of pipe would fit.
At about this time, Doug from PDW called me back. When I originally called him, I was thinking of having the small flange turbo replaced with the large flange model, but at this point, it was too late. Doug went on to say that although II claims the large flange works, in his experience, he has found that on many trucks the stock elbow hits the firewall, and therefore the large flange setup is most often not usable. I wish these two companies would have figured it out.
I had to take the truck to a local muffler shop - yeah, wide-open exhaust! That was interesting. It cost me $85 to fix it, but the didn't have any bent 4" tubing in stainless steel, so I got regular steel. Damn! It's kind of frustrating that I may have been able to save the $180 for the HX40 downpipe and shipping and the $85 if the large flange would have bolted up as II claims. I wish these two companies would have figured it out. Did I say that yet?
Okay, so after that was done, it was time to drive it. After setting my Edge Juice/Attitude on 3 with the highest low-boost fueling setting. BTW, my airbox and exhaust is stock (an MBRP muffler is in the mail).
So how does it drive? Well, whether I stab the throttle or roll into it... .

oh, we're moving now...
Ah... 50 mph... now things get exciting! It pulls pretty well up to the speed limiter. It's a little better than the stock turbo. Peak EGTs are 100-200 lower, and surprisingly (compared to what I've read here), 60-70 mph EGTs are the same. It cools down at idle a lot quicker. I haven't seen over 41 psi of boost, and the cruising speed boost is down a bit.
So what's my opinion at this point? Rather disappointed. Yes, I understand that turbos don't necessarily make power, but the amount lag this thing has really sucks. And many of you claimed this is one of least laggy turbos! I'd hate to have a laggy turbo! Granted, I understand that opening the airbox up will help (even though the sensor thing hasn't sucked down any more than before), and an open muffler would help. But again, I doubt they will help that much. I will see soon enough when I get the muffler - hopefully this week. I just don't want to keep throwing parts at the truck to make it driveable.
If I could do it over again, I would simply keep the stock turbo on the truck. I am keeping the stocker, so I may swap it back in.

I'm sure these trucks could do 140 with 4000rpm's
