X2 I went with the II 366 and I love it it has a wastegate also so no turbo barking that will take out thrust Bering, the twin it Sith the S480 later.Twin the 366. Lol
That's great news Ben glad you keeping the truck .I'm in the planning stages of taking off a single and putting together a twin kit. The fuel needed to spool and keep lit makes for warmer egts than I like when I tow my camper. I feel like twins are the way to go if you plan on towing. I loved my single but don't sled pull anymore so I'm not restricted on turbo/s
