0-60 times are excellent so I'm having trouble with the lag reports.
I've never driven one, but many turbo vehicles (unless they have a tiny or pair of tiny turbos that light REALLY low in the RPM for nearly-instant torque or feature high compression and smaller turbos for a torque-heavy powerband like the Mazda 2.5 turbo motor that is almost diesel-like) then you'll see some lag if you don't brake-torque it off the line. From what I can see from the video below where he tests 0-60 times with and without brake-torqueing an SO-powered Rebel, there is a good half-second difference. As he notes, if you brake-torque it to light the turbos before launching, the Hurricanes are absolute rockets that produce solid 0-60 times. If not, if you just floor it from a standstill, it takes a little bit before the turbos come-on, AKA, turbo lag, and the HO is said to have a hair more lag than the SO motor but come on even harder once the turbos are lit, which is exactly what I'd expect with a point less compression, more peak boost and bigger turbos.
A friend of mine went on the press launch and he said that if you floor the HO out of the hole, it takes off decently well, but about 25-feet out when the turbos lite and the truck is already rolling, it blows the tires off, which is cool in my book! He also mentioned if you brake-torque the HO, that it launches seriously well! He also mentioned that the SO lites the turbos earlier and comes on stronger, sooner but without the super strong top-end surge of the HO, which backs up what more reviewers are saying. The below video has a 0-60 sprint of the HO with brake-torqueing it and it went 0-60 in something like 4.7 seconds!
0-60 with and without brake-torquing an SO: If it doesn't start at the right place, FF to 32:31
