HPT does some stuff on these trucks that EFILive does not. Like the TCC of a 4L80 staying locked after you lift off the throttle and telling it if it's 2wd or 4wd and 4lo shift points so 4lo actually works after a 411 swap.
I think you may have these two products mixed up, or maybe this used to be the case - but as far as I can tell, I can do both of these things in EFI Live. And I can change VIN's, and pull DPF filters off diesels - both things that HPT cannot do. These were the deciding factors in my purchasing EFI Live over HPT.
