Would the Phat Shaft 66 be a good single turbo 2 run with the Power max cr on a 06? Has any one installed one of these turbos on there truck, maybe like an 05 or newer, sure would like 2 here some thoughts on these turbos!!
Totally depends on what you want to do with your truck as well as how you drive!
My opinion based on starting with a HTB2/62/12 followed by a HTB2/62/14 followed by a SPS 66 and now finally with a SPS 62 on my 2003 truck:
SPS 66 for all out drag racing, sled pulling, top end high power that's cool EGT wise
SPS 62 for towing, stoplight-to-stoplight city driving mayhem
I'm the one "testing" the SPS 66 converted to a 62 hybrid. I requested this change after towing with the 66 and wanted to minimize $ spent. With my good fortune

it just so happened that Industrial Injection wanted to test this design anyway. It retains the Super Phat Shaft design of the 66 on the exhaust side and main cartridge, but has the guaranteed surge-less 62 extended tip compressor wheel with matching compressor housing.
Industrial Injection is also experimenting with some twins so the 62 will give a good base for a nice "towing twins" set-up - just thinking ahead a bit

!
Anyhow, the above is just my opinion for whatever it's worth. Do a search, especially in the past 3 months, and you'll find more than enough information to make your decision even more confusing.
