it says v1 in his header. so. that what he has. 1.47v. You need to have this one to get v2. 1.47v is the main procede component. v2 is a tiny little upgrade that gives you only 30 more hp. 1.47v gives you the 50-60 hp and 100 rwtq. So v2 gives you 30 more on top of 1.47v. v2 is just an add on too the procede 1.47v. I have them for sale as well.
