I just bought one and love it. Honestly the only thing I miss about the Duramax was a little smoother ride. Mine is a 15 so I have the regular vgt turbo not the stupid twin compressor one. I loved mine at stock power but now that it's tuned it's even better. The Duramax feel a little more sporty. Probably because they're lower and lighter. But it's still no slouch. It pulls awesome, the exhaust brake is ridiculous, 20+ psi braking boost just in tow haul. If you manually downshift and wind it up over 3k rpms it'll build close to 30. The electric rear locker has already saved my ass twice. All in all I'd do it again, but I'd try to get into a 15 or 16 for the better turbo.
