Yes and no.


For a few updates there is a visual n audio gap online where the car is hybrid power but looks normal to everybody online except when they see what it can do, when cars are reset offline (pretty stupid, it should be the other way around, but anyways)

GT6HE has an anti reset that in 1.15 worked for both off and online, but 4.70 brings strict CFW banning, It's hard to be certain if GT6HE will raise a flag but word on the net is that any rtm flags a possible ban, it's still good for offline use. Going online with hacked cars I don't think will get you a console ban, just a PSN name bann, but RTM while on PSN like GT6HE anti reset might trigger a CFW bann.

Honestly a lot of people act like they have the solution until they get banned too. I haven't found a thread that actually separates the real bannings from the reasons people think they got banned, such as myself as I thought gT6 was my reason, it turns out to more likely be spoofed firmware. There is no thread listing the CFW with spoof that's certain not to just get banned on PSN as of 4.70 and everybody on PSN is a test subject
